Plant genes encoding flavonoid-3', 5'-hydroxylase

TECHNICAL FIELD
The present invention relates to a technique to breed plants or plant cells using recombinant DNA technology. More particularly, the present invention relates to a technique to breed novel plant cells or novel plants which show exogenous pigment patterns by transforming plant cells or plants with a recombinant DNA containing a DNA which encodes a polypeptide having flavonoid-3',5'-hydroxylase activity (hereinafter also referred to as the DNA encoding flavonoid-3',5'-hydroxylase).
BACKGROUND ART
Crossing between varieties has been conventionally employed as a method for altering the color of flowers and fruits of plants. However, crossing is carried out between varieties of the same genus, and usually of the same species, and therefore, it is extremely difficult to give specific colors to certain plant species. For example, in spite of longtime efforts of breeders, no one has yet successfully bred a blue rose or a blue carnation.
In recent years, recombinant DNA technology has enabled plant breeding between different species or genus, and it is expected to breed new plants having unprecedented pigment patterns which can not be obtained by the conventional breeding methods by crossing (Plant Molecular Biology, vol.13, p.287-294, 1989). For example, it is reported that petunia showing unprecedented brick-red color on flowers was bred by cloning a gene encoding dihydroflavonol-4-reductase, which is an enzyme participating in pigment biosynthetic pathway, from maize and introducing it into petunia (Japanese Published Unexamined Patent Application No. 2305/90; Nature, vol.330, p.677-678, 1987). Further, a report has been made of a case in which new pigment patterns were produced by introducing the chalcone synthase gene of petunia at the sense or anti-sense orientation to partially inhibit the expression of the gene (Nature, vol.333, p.866-869, 1988; The Plant Cell, vol.2, p.279-289, 1990; The Plant Cell, vol.2, p.291-299, 1990).
Biosynthetic pathways for anthocyanins, which contribute to blue or red color of flowers, have been studied genetically and biochemically in detail using petunia and others (Petunia, Edited by K. C. Sink, Springer Verlag, p.49-76, 1984; The Flavonoids, Edited by J. B. Harborne, Chapman and Hall, p.399-425, 1988; Molecular Approaches to Crop Improvement, Edited by E. S. Denis and D. J. Rewerin, Springer Verlag, p.127-148, 1991). As a result of these studies, it is shown that the presence/absence of hydroxyl group at the 3'- and 5'-positions of the B ring of anthocyanin greatly affects the color of flowers, and also it is shown that, generally, the blue color of flowers is intensified as the B ring is hydroxylated in a higher degree. The hydroxylation of the B ring of anthocyanins occurs at the stage of their precursors, flavanones or dihydroflavonols. As enzymes which catalyze this hydroxylation, two types of enzyme have been known; flavonoid-3'-hydroxylase which hydroxylates only the 3'-position of the B ring, and flavonoid-3',5'-hydroxylase which hydroxylates both the 3'- and 5'-positions. Petunia with blue flowers has both the enzymes, but that with red flowers has only the former one. Plants like roses, carnations, and chrysanthemums do not have anthocyanins which have B ring hydroxylated at both the 3'- and 5'-positions, and therefore are considered not to have the latter type of enzyme.
These hydroxylases are localized in the microsomal membrane and require NADPH as a coenzyme. They are presumed to be members of the cytochrome P450 enzyme group on the basis of their behavior against various inhibitors (The Flavonoids, Edited by J. B. Harborne, Chapman and Hall, p.399-425, 1988; Molecular Approaches to Crop Improvement, Edited by E. S. Denis and D. J. Rewerin, Springer Verlag, p.127-148, 1991).
Cytochrome P450 is an enzyme group which is widely distributed among eucaryotes and procaryotes and which is involved in the biosynthesis of important lipids such as steroids and in the oxidative metabolism of lipophilic substances. In higher animals, it forms a super family consisting of one hundred or more molecular species (J. Biol. Chem., vol.266, p.13469-13472, 1991; Pharmacol. Rev., vol.40, p.243-288, 1988). In plants, cinnamic acid-4-hydroxylase and kaurene oxidase are considered to belong to the cytochrome P450 group (Plant Physiol., vol.96, p.669-674, 1991). Further, a gene encoding a cytochrome P450 enzyme whose function is unknown has been cloned from avocado (Proc. Natl. Acad. Sci. USA, vol.87, p.3904-3908, 1990). As a result of the comparison of the amino acid sequences of various types of cytochrome P450 enzymes, it is known that the sequence of the heme-binding site is conserved (Proc. Natl. Acad. Sci. USA, vol.85, p.7221-7225, 1988; Pharmacol. Rev. vol.40, p.243-288, 1988).
In petunia, flavonoid-3',5'-hydroxylase is encoded by two dominant genes called Hf-1 and Hf-2. The enzymes encoded by the genes are isozymes, and the degree of expression of Hf-1 is higher (Petunia, Edited by K. C. Sink, Springer Verlag, p.49-76, 1984). Further, characteristics of said enzyme of Verbena have been reported (Z. Naturforschung, vol.37c, p.19-23, 1982).
It is also reported that 3',5'-hydroxylase, a key enzyme in the biosynthesis of delphinidin, which is a blue pigment in petunia, has been successfully cloned (Nikkei Biotech, Aug. 26, 1991). However, no report has been made yet of a case in which the cloned gene of said enzyme is allowed to express in a plant to alter pigments in the plant.
SUMMARY OF THE INVENTION
The present invention provides a DNA which encodes a polypeptide having flavonoid-3',5'-hydroxylase activity which is represented by the amino acid sequence shown by SEQ ID NO: 1, 63 or 64, a DNA which hybridizes with said DNA, a recombinant DNA constructed by incorporating any of these DNAs or a part of their sequences into a vector DNA, and plant cells or plants which carry said recombinant DNA.
It is possible to breed plants having novel pigment patterns by introducing said DNA, i.e., a DNA that encodes a polypeptide having flavonoid-3',5'-hydroxylase activity, into plant cells or plants by the use of recombinant DNA technology.
The DNA of the present invention may be any DNA which encodes a polypeptide having flavonoid-3',5'-hydroxylase activity, i.e., a DNA which encodes a polypeptide represented by the amino acid sequence shown by SEQ ID NO: 1, 63 or 64, or a DNA which hybridizes with said DNA (hereinafter referred to as hDNA). The hDNA may be any DNA which hybridizes with the DNA encoding the polypeptide represented by the amino acid sequence shown by SEQ ID NO: 1, 63 or 64 in 2.times.SSC (0.3 M sodium chloride, 0.03 M sodium citrate, pH 7.0) at 50.degree. C.
The DNA which encodes the polypeptide represented by the amino acid sequence shown by SEQ ID NO: 63 or 64 hybridizes with the DNA which encodes the polypeptide represented by the amino acid sequence shown by SEQ ID NO: 1 under the above-mentioned conditions.
Other examples of the DNAs of the present invention include DNAs wherein a part of the nucleotide sequence of the above-mentioned DNAs is deleted or replaced with other nucleotide sequences, as far as such DNAs encode a polypeptide having flavonoid-3',5'-hydroxylase activity.
Examples of the DNA sources include a genomic DNA of plants which have flavonoid-3',5'-hydroxylase, and a cDNA which is synthesized from an mRNA extracted from the expression sites of said enzyme using a reverse transcriptase. Examples of the plants having said enzyme include petunia (Solanaceae), pansy (Violaceae), primrose (Primulaceae), delphinium (Ranunculaceae), sweet pea (Leguminosae), Japanese gentian (Gentianaceae), balloon flower (Campanulaceae), forget-me-not (Boraginaceae), hydrangea (Saxifragaceae), verbena (Verbenaceae), dayflower (Commelinaceae), iris (Iridaceae), hyacinth (Liliaceae), Russell prairie gentian (Gentianaceae), and campanula (Campanulaceae).
In the present invention, on the basis of the presumption that flavonoid-3',5'-hydroxylase is a member of the cytochrome P450 family, DNA sequences encoding the amino acid sequence of the heme-binding site of cytochrome P450 (hereinafter referred to as the core sequence) are amplified and isolated using the PCR method.
The core sequence is the region that shows high homology among different molecular species of cytochrome P450 and among those of different organisms. More than 80% of the sequences for cytochrome P450 which have been ever isolated have the core sequence shown in FIG. 1 (DNASIS.TM. Data Base CD, 009-1 and 2, Hitachi Software Engineering Co., Ltd., 1990). DNA sequences which can encode the amino acid sequence of the region indicated by arrows are hypothesized. Then, in order to amplify and isolate the DNA sequences encoding this region by the PCR method, 16 types of sense primers shown by SEQ ID NO: 2 to 17, and 12 types of antisense primers shown by SEQ ID NO: 18 to 29 are chemically synthesized. The sense primers are synthetic oligonucleotides each consisting of 18 bases. Each sense primer has, at the 3' end side, one of the 16 types of 8-base DNA sequences encoding Pro-Phe-Gly or Pro-Phe-Ser and lacking the DNA base that corresponds to the third base of the codon for Gly or Ser. The sense primer has a 10-base sequence containing a recognition site for a restriction enzyme, EcoRI, at the 5' end side. The antisense primers are synthetic oligonucleotides each consisting of 18 bases. Each antisense primer has, a t the 3' end side, a complementary DNA sequence for one of the 12 types of 8-base DNA sequences encoding Cys-Xxx-Gly wherein Xxx represents either Ile, Met, Leu, Phe, Val, Ala, or Pro, and lacking the DNA base that corresponds to the third base of the codon for Gly. The DNA base corresponding to the third base of the codon for Xxx may be any one of A, C, G and T represented by N. The antisense primer has a 10-base sequence containing a recognition site for a restriction enzyme, BamHI, at the 5' end side.
By the use of PCR in which these synthetic DNA primers are employed in combination, various DNA fragments which encode the core sequence can be amplified and isolated, and their DNA sequences can be determined. As cytochrome P450 forms a super family which consists of various molecular species, it is expected that various types of core sequences can be obtained from one template DNA. During the process of the present invention, 15 types of core sequences shown by SEQ ID NO: 30 to 44 were obtained.
It is necessary to make a presumption as to which core sequence is the target sequence among the thus obtained core sequences. In the present invention, the target sequence is presumed by investigating whether the expression/non-expression of each core sequence is genetically linked to the presence/absence of said enzyme activity. In order to investigate the genetic linkage, a petunia which originally has said enzyme (a blue flower cultivar) is backcrossed with a mutant petunia variety which lacks said enzyme (a red flower cultivar) to produce a genetically segregating population (1:1) regarding the presence/absence of said enzyme. Then, the mode of expression of each core sequence in the petals of individual plants in this population is investigated. If the mode of expression of any core sequence agrees with (is genetically linked with) the presence/absence of said enzyme, the core sequence is presumed to be a part of the gene encoding said enzyme.
In order to investigate whether a core sequence is expressed in the petals, the present invention uses a method called SSP (single specific primer).multidot.polymerase chain reaction (PCR)SSP.multidot.PCR is a method described in Biochemistry Biophysics Research Communication, vol.167, p.504-506, 1990. By the use of this method, it is possible to amplify a DNA sequence flanking a core sequence and to determine the presence/absence of the corresponding product. First, specific DNA primers are synthesized based on the DNA sequences encoding the core sequences. In the present invention, 15 types of DNAs (K primers 01 to 15) shown by SEQ ID NO: 45 to 59 were synthesized and used as the specific DNA primers. Then, cDNAs are prepared from the petals of each petunia plant in the backcrossed population, digested with appropriate restriction enzymes, and then ligated with appropriate double-strand synthetic DNA (called cassette) which had the corresponding cleaved ends using a ligase to prepare templates. In the present invention, synthetic DNAs shown by SEQ ID NO: 60 and 61 were annealed and used as the cassette. The synthetic DNA shown by SEQ ID NO: 60 was also used as the primer for the cassette. With the template DNA ligated to the cassette, PCR was carried out between the specific primer and the primer for the cassette, whereby the DNA sequence flanking the core sequence is amplified. The presence/absence of its product reflects the expression/non-expression of the core sequence.
As a result of the search in the petunia population obtained by the backcrossing, it was revealed that the presence/absence of a product (approximately 85 bp) which was amplified by SSP.multidot.PCR using the specific primer (K14) shown by SEQ ID NO: 58 was completely linked with the presence/absence of said enzyme activity. As this primer was designed based on the core sequence shown by SEQ ID NO: 43, this sequence is assumed to be the core sequence of said enzyme. On the basis of SEQ ID NO: 43, the primer (J14) shown by SEQ ID NO: 62 was synthesized and SSP.multidot.PCR was carried out. As a result, the presence/absence of a product of approximately 280 bp was completely linked with the presence/absence of the enzyme activity. This result strongly suggests that the core sequence shown by SEQ ID NO: 43 is the target sequence.
The product of approximately 280 bp thus amplified is assumed to be a part of the cDNA sequence that encodes said enzyme. The full length cDNA sequence shown by SEQ ID NO: 1 can be obtained by preparing petunia flower cDNA library according to the method described in a book by Maniatis et al., and then searching the library using the above-mentioned product as a probe. If the expression of the obtained sequence in a plant which originally does not have said enzyme results in the detection of said enzyme activity in the plant, it will be proved that this sequence is the DNA sequence encoding the polypeptide having said enzyme activity. In the present invention, the DNA shown by SEQ ID NO: 1 was introduced into tobacco and petunia cultivars both of which do not have said enzyme, and expressed. As a result, said enzyme activity was detected in both plants, and thus the DNA was proved to be the DNA encoding the polypeptide having said enzyme activity.
Cloning of DNAs can be carried out using a material such as a cDNA which is synthesized based on an mRNA extracted from the petals of petunia using a reverse transcriptase.
DNA cloning and DNA analysis can be carried out according to general techniques described in Molecular Cloning a Laboratory Manual Second Edition, J. Sambrook, E. F. Frisch, T. Maniatis, Cold Spring Harbor Laboratory Press, 1989 (hereinafter referred to as the book by Maniatis et al.), and the like.
PCR can be carried out according to ordinary techniques described in PCR Technology, Edited by H. A. Ehrlich, Stockton Press, 1989, PCR Protocols, Edited by M. A. Innis, D. H. Gerfand, J. J. Sninsky, and T. J. White, Academic Press, 1990, and the like.
Determination of nucleotide sequences can be carried out according to methods using the Taq Dideoxy.TM. Terminator Cycle Sequencing Kit (ABI Co., Ltd.) and the Model 373A DNA Sequencing System (ABI Co., Ltd.), and the like.
DNA fragments encoding polypeptides which have analogous sequences and said enzyme activity can be cloned from any of the plants mentioned above as the DNA source by an ordinary method using, as a probe for hybridization, the whole or a part of the DNA sequence shown by SEQ ID NO: 1 which encodes the polypeptide having said enzyme activity and is derived from petunia as above.
In the present invention, according to the above-mentioned method, a DNA which encodes a polypeptide having the amino acid sequence shown by SEQ ID NO: 63 has been cloned from Russell prairie gentian, and a DNA which encodes a polypeptide having the amino acid sequence shown by SEQ ID NO: 64 has been cloned from campanula.
New coloration can be introduced into a host plant which does not have said enzyme by introducing a DNA fragment which encodes a polypeptide having said enzyme activity into the host plant, allowing it to express, and thereby hydroxylating the 3'- and 5'-positions of anthocyanin pigments. Examples of such host plants include rose (Rosaceae), carnation (Caryophyllaceae), petunia (Solanaceae), tobacco (Solanaceae), chrysanthemum (Compositae), stock (Cruciferae), begonia (Begoniaceae), snapdragon (Scrophulariaceae), camellia (Theaceae), lily (Liliaceae), and orchid (Orchidaceae).
Further, in plant species which originally have said enzyme, the enzyme activity can be inhibited by introducing said DNA fragment at the antisense or sense orientation and allowing it to express (Nature, vol.333, p.866-869, 1988; The Plant Cell, vol.2, p.279-289, 1990; The Plant Cell, vol.2, p.291-299, 1990). By application of such methods, breeding of a plant species having an unprecedented pigment pattern can be achieved.
In order to introduce the DNA fragment which encodes the polypeptide having said enzyme activity into plants and allow it to express, it is necessary to introduce an appropriate promoter at the site upstream of the region encoding the polypeptide having said enzyme activity. An example of a promoter that works in plants is 35 S promoter of Cauliflower Mosaic Virus (CaMV) (Cell, vol.21, p.285-294, 1980). An example of a promoter that acts site-specifically is the promoter of petunia chalcone synthase (CHS) gene which works strongly only in the petals (Plant Molecular Biology, vol.15, p.95-109, 1990). The above-mentioned DNA fragment can be expressed in plants by ligating such a promoter. When a DNA which encodes the polypeptide having said enzyme activity is cloned from the genomic DNA, it may have been linked with an inherent promoter, and in such cases, there is no need to further link it with another promoter.
Further, efficient expression can be expected by introducing a terminator for the termination of transcription at the site downstream of the region encoding the polypeptide having said enzyme activity (EMBO Journal, vol.7, p.791-799, 1988).
In order to select plant cells or plants in which the DNA has been introduced, it is preferable to introduce an appropriate marker into the DNA. Examples of such markers include the kanamycin resistance gene and the hygromycin resistance gene (Plant Molecular Biology, vol.5, p.299-302, 1985). When a microorganism belonging to the genus Agrobacterium is used to introduce the DNA into plant cells or plants, it is necessary to attach the border sequences derived from Ti plasmid at both ends of the sequence to be inserted into plant chromosomes (Nature, vol.313, p.191-196, 1985). Further, it is necessary to link the insert sequence with a sequence that allows stable retention of plasmids in a cell of a microorganism belonging to the genus Agrobacterium. An example of an expression vector for plants which meets the above-mentioned requirements is pBI121 (Clonetech Co., Ltd.).
Examples of methods for introducing said DNA fragment inserted in a vector as described above into plants and obtaining genetically stable transformed plants include: 1) a method for dicotyledons in which the DNA is introduced via Agrobacterium tumefaciens, the bacterium causing crown gall disease (Methods in Enzymology, vol.118, p.627-640, 1986); 2) a method in which the DNA is pelted in conjunction with microparticles of substances such as gold and tungsten at plant cells at a high speed to be incorporated into cell nuclei and then into chromosomes (the high-speed microparticle method; Plant Molecular Biology, vol.11, p.433-439, 1989; Bio/Technology, vol.9, p.1080-1085, 1991); and 3) a method in which the DNA is introduced in conjunction with calcium chloride and polyethylene glycol into protoplasts which have been prepared with cell wall-degrading enzymes (Nature, vol.296, p.72-74, 1982; Nature, vol.319, p.791-793, 1986). The method 1) can be efficiently carried out by incorporating the insert DNA into a binary vector such as pBI121 (Nucleic Acids Research, vol.12, p.8711-8721, 1984). According to the method 2), the DNA can be introduced into plants which cannot be infected with a microorganism belonging to the genus Agrobacterium such as monocotyledons. After the introduction of said DNA fragment incorporated into a vector into plant cells according to the methods described above, plant cells in which the introduced DNA is stably retained in the chromosome are selected by utilizing appropriate marker genes such as those for drug resistance. By inducing the differentiation of such plant cells, transformed plants having novel pigment patterns can be obtained.
In the thus obtained transformed plants, the DNA fragments introduced are retained with genetic stability. In other words, said DNA fragments can be maintained semi-persistently through propagation by vegetative reproduction, or by seeds obtained through self-pollination or cross pollination.
Further, it is possible to breed new cultivars which have pigment patterns different from those of the first-generation transformants by crossing the transformants with conventional cultivars to combine their genes.
Thus, a technique is provided which enables the production of unprecedented cultivars having blue or purple flowers by allowing plants having no anthocyanin pigments whose B ring is hydroxylated at both the 3'- and 5'-positions, for example, roses and carnations, to synthesize such pigments.

BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows the core sequence which is common to more than 80% of the known amino acid sequences for cytochrome P450.

DETAILED DESCRIPTION OF THE INVENTION
EXAMPLE 1
PCR Amplification and Isolation of the Core Sequences of Cytochrome P450 Genes and Their Sequencing
(1) Synthesis of Primers
A part of the gene sequence of cytochrome P450 was amplified and isolated by the polymerase chain reaction (PCR) in the following manner. Cytochrome P450 forms a super family consisting of various molecular species, but the similarity in the amino acid sequence among these molecular species is not so high. However, the sequences of the heme-binding region (core sequence) are relatively common.
More than 80% of the sequences for cytochrome P450 ever isolated have the core sequence shown in FIG. 1. DNA sequences which could encode the amino acid sequence of the region indicated by arrows were hypothesized. Then, in order to amplify and isolate the DNA sequences encoding this region by the PCR method, primer DNAs were chemically synthesized using the DNA synthesizer, Cyclone Plus.TM. (manufactured by Milligen/Biosearch). Thus, 16 types of sense primers shown by SEQ ID NO: 2 to 17, and 12 types of antisense primers shown by SEQ ID NO: 18 to 29 were synthesized.
The sense primers are synthetic oligonucleotides each consisting of 18 bases. Each sense primer has, at the 3' end side, one of the 16 types of 8-base DNA sequences encoding Pro-Phe-Gly or Pro-Phe-Ser and lacking the DNA base that corresponds to the third base of the codon for Gly or Ser. The sense primer has a 10-base sequence containing a recognition site for a restriction enzyme, EcoRI, at the 5' end side. The antisense primers are synthetic oligonucleotides each consisting of 18 bases. Each antisense primer has, at the 3' end side, a complementary DNA sequence for one of the 12 types of 8-base DNA sequences encoding Cys-Xxx-Gly wherein Xxx represents either Ile, Met, Leu, Phe, Val, Ala, or Pro, and lacking the DNA base that corresponds to the third base of the codon for Gly. The DNA base corresponding to the third base of the codon for Xxx may be any one of A, C, G and T represented by N. The antisense primer has a 10-base sequence containing a recognition site for a restriction enzyme, BamHI, at the 5' end side.
Each primer was used in a 5 .mu.M aqueous solution.
(2) Extraction of mRNAs from the Petals of Petunia
Extraction of mRNAs from the petals of petunia was carried out according to a modification of the method described in Analytical Biochemistry, vol.163, p.16-20, 1987. That is, petals were cut off from buds of petunia [Petunia hybrida cv. Falcon Blue (Sakata Seed Corporation)] which had been grown in a greenhouse. Ten grams (wet weight) of the petals was put into a mortar, frozen by pouring liquid nitrogen, and then ground with a pestle. To the ground petals were added 20 ml of RNA extraction buffer [8 M guanidine hydrochloride, 20 mM Mes buffer (pH 7.0), 20 mM EDTA, 50 mM mercaptoethanol] and then 10 ml of phenol/chloroform/isoamyl alcohol (25:24:1) mixture, and mixed well. The resulting mixture was centrifuged at 10,000.times.g for 10 minutes, and the upper layer was collected and mixed well with 20 ml of phenol/chloroform/isoamyl alcohol (25:24:1) mixture. The resulting mixture was centrifuged at 10,000.times.g for 10 minutes, and the upper layer was collected. Then, 14 ml of ethanol and 4 ml of 1 M acetic acid were added to the upper layer, and the mixture was allowed to stand at -70.degree. C. for one hour, followed by centrifugation at 10,000.times.g for 10 minutes. The precipitate was separated, dissolved in 10 ml of water, and then mixed with 3 ml of 10 M lithium chloride. The resulting mixture was allowed to stand at 4.degree. C. for 2 hours, and centrifuged at 10,000.times.g for 10 minutes. The precipitate was separated, washed with 10 ml of 70% ethanol, and then dried under vacuum. The dried product was dissolved in 1 ml of elution buffer [10 mM Tris hydrochloride buffer (pH 7.5), 1 mM EDTA, 0.1% sodium dodecyl sulfate (SDS)], and then subjected to purification using 200 .mu.l of oligotex.TM.-dT 30 (Takara Shuzo Co., Ltd.) according to the instructions provided by the manufacturer to give about 3 .mu.g of poly(A)mRNA.
(3) Synthesis of cDNA from Petunia Petal mRNA
A cDNA was synthesized from oligo dT primer using the above-mentioned mRNA as the template and the cDNA Synthesis System Plus RPN1256 (Amersham Co., Ltd.) according to the instructions provided by the manufacturer. About 2 .mu.g of double strand cDNA was obtained.
(4) PCR Amplification of the Consensus Sequence of Cytochrome P450
The above-mentioned cDNA (1 ng) as a template DNA was dissolved in 25 .mu.l of PCR buffer [10 mM Tris hydrochloride buffer (pH 8.3), 1.5 mM magnesium chloride, 25 mM potassium chloride, 0.05% Tween 20, 100 .mu.M dATP, 100 .mu.M dCTP, 100 .mu.M dGTP, 100 .mu.M dTTP]. The solution was put in a 0.5-ml microcentrifugation tube, and as primers, 1 .mu.l of a sense primer (one type) and 1 .mu.l of an antisense primer (one type) both of which were prepared in the step (1) were added thereto. To the mixture was added 0.5 unit of Taq DNA polymerase (Perkin-Elmer Cetus), and 10 .mu.l of mineral oil was layered over the mixture. The reaction was carried out using the DNA Thermal Cycler (Perkin-Elmer Cetus) with the cycle program set as follows; 30 seconds at 93.degree. C. and 1 minute at 37.degree. C. for 3 cycles, followed by 30 seconds at 93.degree. C. and 1 minute at 55.degree. C. for 37 cycles.
PCR was carried out under the above conditions for each of all the 192 combinations of 16 sense primers and 12 antisense primers.
PCR was carried out by reference to PCR Technology, edited by H. A. Ehrlich, Stockton Press, 1989, and PCR Protocols, edited by M. A. Innis, D. H. Gerfand, J. J. Sninsky, and T. J. White, Academic Press, 1990.
(5) Cloning of PCR Products
The products of the above reaction were subjected to 10% polyacrylamide gel electrophoresis and stained with ethidium bromide according to the method described in the book by Maniatis et al. As a result, a DNA band of approximately 50 bp was detected for 23 among the 192 combinations of sense primers and antisense primers. Portions containing the DNA band were cut out from the gel, and DNAs were extracted and purified according to the methods described in the book by Maniatis et al. Each of the obtained DNAs was dissolved in 50 .mu.l of H buffer [50 mM Tris hydrochloride buffer (pH 7.5), 10 mM magnesium chloride, 1 mM dithiothreitol, 100 mM sodium chloride]. To the solution were added 10 units of the restriction enzyme BamHI (Takara Shuzo Co., Ltd.) and 10 units of the restriction enzyme EcoRI (Takara Shuzo Co., Ltd.), and the reaction was carried out at 37.degree. C. for 3 hours. After addition of 150 .mu.l of ethanol, the reaction mixture was allowed to stand at -80.degree. C. for 10 minutes, and then centrifuged at 10,000.times.g for 10 minutes. The obtained precipitate was washed with 200 .mu.l of 70% ethanol and dried under vacuum. The obtained DNA was dissolved in 10 .mu.l of TE buffer [10 mM Tris hydrochloride buffer (pH 7.5), 1 mM EDTA].
The plasmid vector pUC19 (Takara Shuzo Co., Ltd.) (5 .mu.g) was dissolved in 50 .mu.l of H buffer, and 10 units of the restriction enzyme BamHI (Takara Shuzo Co., Ltd.) and 10 units of the restriction enzyme EcoRI (Takara Shuzo Co., Ltd.) were added. The reaction was carried out at 37.degree. C. for 3 hours. After addition of 150 .mu.l of ethanol, the reaction mixture was allowed to stand at -80.degree. C. for 10 minutes, and then centrifuged at 10,000.times.g for 10 minutes. The obtained precipitate was washed with 200 .mu.l of 70% ethanol and dried under vacuum. The obtained vector DNA was dissolved in 100 .mu.l of TE buffer.
The vector solution thus prepared (1 .mu.l) was mixed with the solution containing the DNA fragment of approximately 50 bp (10 .mu.l) prepared above, and subjected to ligation at 16.degree. C. for 30 minutes using the DNA Ligation Kit (Takara Shuzo Co., Ltd.) according to the instructions provided by the manufacturer. The volume of the reaction mixture was 60 .mu.l. Highly competent cells of E. coli JM109 (Toyobo Co., Ltd.) were transformed with 2 .mu.l of the reaction mixture according to the instructions provided by the manufacturer. According to the method described in the book by Maniatis et al., the cells were cultured at 37.degree. C. for 20 hours on X-gal ampicillin LB agar medium [1% Bacto Tryptone (Difco Laboratories), 0.5% Bacto Yeast Extract (Difco Laboratories), 1% sodium chloride, 40 .mu.g/ml X-gal, 40 .mu.g/ml isopropyl-1-thio-.beta.-D-galactopyranoside (IPTG), 100 .mu.g/ml ampicillin, 1.5% Bacto Agar (Difco Laboratories)]. One of the formed white colonies was isolated and cultured, and plasmid DNA was extracted from the culture and purified.
(6) Determination of DNA Sequences of PCR Products
The nucleotide sequence of the insert fragment in each of the 108 clones prepared as described above were determined using the Taq Dideoxy.TM. Terminator Cycle Sequencing Kit (ABI) and the Model 373A DNA Sequencing System (ABI) according to the instructions provided by the manufacturer. As a result, 15 types of core sequences shown by SEQ ID NO: 30 to 44 were determined for the cytochrome P450 genes.

Production of Petunia Backcrossed Population
(1) Analysis of Pigments in the Petals
Pigments in the petals were analyzed after converting anthocyanins into anthocyanidins according to the method described in Phytochemical Methods, Second Edition, edited by J. B. Harbone, p.64, Chapman and Hall, 1989. That is, 0.1 to 0.5 g of the petals was cut off and 1 ml of 2N hydrochloric acid was added. The mixture was heated at 95.degree. C. for 40 minutes, and then brought to room temperature. After addition of 300 .mu.l of ethyl acetate followed by thorough mixing, the mixture was allowed to stand still, and the upper ethyl acetate layer was discarded. The residue was heated at 80.degree. C. for 3 minutes to evaporate ethyl acetate, and then brought to room temperature. After addition of 100 .mu.l of isoamyl alcohol followed by thorough mixing, the mixture was allowed to stand still, and the upper isoamyl alcohol layer was collected. Aliquots of 1 to 5 .mu.l of the obtained solution were spotted on a cellulose thin layer plate (Merck & Co., Inc.) and chromatographed using Solvent 1 (conc.hydrochloric acid:acetic acid:water=3:30:10) or Solvent 2 (n-butanol:acetic acid:water=4:1:5) to identify anthocyanidins based on the Rf values and coloration of the pigment spots. Separately, analysis was also carried out using the Hitachi Ion Chromato System (Model L6200 pump and Model L4200 detector), YMC-Pack ODS-A Reversed Phase Column (YMC), and mobile phase consisting of water, acetic acid and methanol (71:10:19) [New High Performance Liquid Chromatography, Application II, p.528, Hirokawa Shoten, 1983]. Anthocyanidins were identified by using commercially available cyanidin, delphinidin, peonidin, and maruvidin (all produced by Extrasynthese) as standards.
(2) Production of Petunia Backcrossed Population
Crossing of petunia was carried out according to the method described in Petunia, edited by K. C. Sink, p.180-202, Springer Verlag, 1984. A blue flower petunia cultivar, Purple Joy (NPI Seeds) was crossed with a red flower petunia cultivar, Falcon Red (Sakata Seed Corporation) to obtain hybrids. The hybrids were backcrossed with Falcon Red, and anthocyanidins in the petals of the obtained hybrids were analyzed. A hybrid plant which had delphinidin as the anthocyanidin component was selected and then backcrossed with Falcon Red. After such backcrossing was repeated four times in total, anthocyanidins in the petals of 18 plants of the obtained hybrid population were analyzed. Among them ten hybrids had delphinidin (delphinidin-type) as anthocyanidin and eight hybrids had cyanidin (cyanidin-type). The color of petals of the former type was grayish purple, and that of the latter was red.
(3) Detection of Flavonoid-3',5'-hydroxylase Activity
Detection of flavonoid-3',5'-hydroxylase activity was carried out according to a modification of the method described in Z. Naturforsch, vol.37c, p.19-23, 1982. That is, 5 g (wet weight) of petals of buds was disrupted using mortar and pestle at 0.degree. C., with 2.5 g of quartz sand (Sigma), 2.5 g of Dow X 1.times.2 (The Dow Chemical), and 10 ml of buffer for enzyme extraction [0.1 M potassium phosphate buffer (pH 7.5), 20% glycerol, 10 mg/ml sodium ascorbate]. After centrifugation at 12,000.times.g for 20 minutes, the obtained supernatant (10 ml) was mixed with 0.4 ml of 1 M magnesium chloride. The mixture was allowed to stand at 0.degree. C. for 10 minutes, and centrifuged at 17,000.times.g for 20 minutes to obtain precipitate. The precipitate was suspended in a small quantity of the buffer for enzyme extraction to make a final volume of 500 .mu.l, and the suspension was used as the microsome fraction.
An aliquot of 100 .mu.l of the microsome fraction was mixed with 400 .mu.l of a reaction mixture [0.1 M potassium phosphate buffer (pH 7.5), 20% glycerol, 10 mg/ml sodium ascorbate, 0.25 mM NADPH (Sigma), 0.25 mM dihydroquercetin (Sigma)], and allowed to react at 25.degree. C. for 30 minutes. After addition of 250 .mu.l of ethyl acetate, the mixture was allowed to stand still, and the upper layer (ethyl acetate layer) was collected, followed by evaporation of ethyl acetate. The residue was dissolved in 10 .mu.l of ethyl acetate, and an aliquot of 5 .mu.l of the solution was spotted on a cellulose thin layer plate (Merck & Co., Inc.) and chromatographed using Solvent 3 (chloroform:acetic acid:water=10:9:1). Flavonoids detected under the UV light were identified based on the Rf values. As a result, it was shown that dihydroquercetin had been converted into dihydromyricetin by the action of flavonoid-3',5'-hydroxylase.
Among the plants of the above-mentioned population obtained by backcrossing, said enzyme activity was detected in the delphinidin-type plants. On the other hand, it was not detected in the cyanidin-type plants. Further, said enzyme activity was detected in Falcon Blue (Sakata Seed Corporation) and Purple Joy (NPI Seeds), which were blue flower petunia cultivars, but was not detected in Falcon Red (Sakata Seed Corporation) and Falcon Salmon (Sakata Seed Corporation), which were red flower petunia cultivars.
EXAMPLE 3
SSP-PCR Using the Core Sequence of Cytochrome P450
(1) Synthesis of K Primers
On the basis of 15 types of the core sequences for cytochrome P450 shown by SEQ ID NO: 30 to 44 which were obtained in Example 1 (6), 15 types of PCR primers shown by SEQ ID NO: 45 to 59 were chemically synthesized using the DNA Synthesizer Cyclone Plus (Milligen/Biosearch). Each primer was used in a 5 .mu.M aqueous solution. The primers were named K01 to K15 primers, respectively, and collectively referred to as K primers. K primers are synthetic DNA primers each having a 17-base sequence which starts from the codon for glycine located at the C-terminus of the amino acid sequence of the core and extends toward the N-terminus, and correspond to the sequences from the 32nd nucleotide to the 16th nucleotide in the core DNA sequences shown by SEQ ID NO: 30 to 44.
(2) Synthesis of a Cassette and a Primer for the Cassette
Oligonucleotides indicated by SEQ ID NO: 60 and 61 were chemically synthesized using the DNA Synthesizer Cyclone Plus (Milligen/Biosearch), and a 20 .mu.M aqueous solution of each oligonucleotide was prepared. After 100 .mu.l each of the solutions were mixed, the mixture was heated at 95.degree. C. for 10 minutes, and then kept at 50.degree. C. for one hour to obtain a double strand DNA, which is called a cassette. One end of the cassette forms a cohesive end of CG-protruding type, and therefore, can be efficiently linked with a restriction end digested with restriction enzymes, such as HinPI, MaeII, MspI and TthHB8I.
Separately, a 5 .mu.M aqueous solution of the oligonucleotide shown by SEQ ID NO: 60 was prepared and used as the primer for the cassette.
(3) Synthesis of Petunia Petal cDNA
Four plants of the delphinidin-type and two plants of the cyanidin-type were selected from the backcrossed population produced in Example 2, and cDNAs were synthesized using mRNAs extracted from the petals of each plant according to the methods described in Example 1 (2) and (3). Similarly, cDNAs were synthesized from petals of Falcon Blue, Falcon Red, Falcon Salmon, and Purple Joy.
(4) TthHB8I Digestion of cDNA and Linkage to Cassette
An aliquot of 0.1 .mu.g of each of the ten types of cDNAs obtained in (3) above was dissolved in 50 .mu.l of H buffer, and one unit of the restriction enzyme TthHB8I (Takara Shuzo Co., Ltd.) was added. The reaction was carried out at 65.degree. C. for one hour. Then, the reaction mixture was mixed with 5 .mu.l of phenol/chloroform (1:1) mixture, followed by addition of 150 .mu.l of ethanol. The resulting mixture was allowed to stand at -80.degree. C. for 10 minutes, and centrifuged at 10,000.times.g for 10 minutes. The obtained precipitate was washed with 200 .mu.l of 70% ethanol, and dried under vacuum. The obtained DNA was dissolved in 9 .mu.l of TE buffer.
After adding 1 .mu.l of the cassette to each DNA solution, ligation reaction was carried out at 16.degree. C. for 30 minutes using the DNA Ligation Kit (Takara Shuzo Co., Ltd.) according to the instructions provided by the manufacturer. The volume of the reaction mixture was 60 .mu.l.
(5) PCR Between K Primers and the Primer for Cassette
By the use of each of the above reaction mixtures as a template, the sequence to a near restriction site can be amplified by PCR between a K primer (01 to 15) and the primer for the cassette.
An aliquot of 1 .mu.l of each of the above-mentioned reaction mixtures, which was used as a template, was added to 1 .mu.l of a K primer and 1 .mu.l of the primer for the cassette, and mixed with 25 .mu.l of PCR buffer. The mixture was transferred into a 0.5-ml microcentrifugation tube, 0.5 unit of Taq DNA polymerase (Perkin-Elmer Cetus) was added thereto, and 10 .mu.l of mineral oil was layered over the mixture. The reaction was carried out using the DNA Thermal Cycler (Perkin-Elmer Cetus) for 40 cycles with the cycle profile consisting of 30 seconds at 93.degree. C. and 1 minute at 55.degree. C. According to the methods described in the book by Maniatis et al., the PCR products were subjected to 10% polyacrylamide gel electrophoresis, and DNA bands were stained with ethidium bromide and examined under UV light.
As a result, in the SSP-PCR using K14 primer, a DNA band of about 85 bp was obtained when one of the six types of cDNAs obtained from Falcon Blue, Purple Joy, and four delphinidin-type backcrossed plants was used as the template. On the other hand, the band was not detected when one of the four types of cDNAs obtained from Falcon Red, Falcon Salmon, and two cyanidin-type backcrossed plants was used as the template. That is, it was demonstrated that the presence/absence of the SSP-PCR products of about 85 bp was genetically linked to the presence/absence of said enzyme activity. When the other primers were used, no such product was detected. As the K14 primer was designed based on the core sequence shown by SEQ ID NO: 43, it was suggested that the sequence shown by SEQ ID NO: 43 was a part of the DNA sequence encoding the polypeptide which had said enzyme activity.
(6) Synthesis of J14 Primer
On the basis of the core sequence of cytochrome P450 shown by SEQ ID NO: 43, according to which K14 primer was synthesized, a primer shown by SEQ ID NO: 62 was chemically synthesized using the DNA Synthesizer Cyclone Plus (Milligen/Biosearch). The primer was named J14 primer, and used in a 5 .mu.M aqueous solution.

The reaction was carried out at 37.degree. C. for one hour. Then, the reaction mixture was mixed with 5 .mu.l of phenol/chloroform (1:1) mixture, followed by addition of 150 .mu.l of ethanol. The resulting mixture was allowed to stand at -80.degree. C. for 10 minutes, and centrifuged at 10,000.times.g for 10 minutes. The obtained precipitate was washed with 200 .mu.l of 70% ethanol, and dried under vacuum. The obtained DNA was dissolved in 9 .mu.l of TE buffer. After adding 1 .mu.l of the cassette to each DNA solution, ligation reaction was carried out at 16.degree. C. for 30 minutes using the DNA Ligation Kit (Takara Shuzo Co., Ltd.) according to the instructions provided by the manufacturer. The volume of the reaction mixture was 60 .mu.l.
(8) PCR Between J14 Primer and the Primer for Cassette
An aliquot of 1 .mu.l of each of the above-mentioned reaction mixtures, which was used as a template, was added to 1 .mu.l of J14 primer and 1 .mu.l of the primer for the cassette, and mixed with 25 .mu.l of PCR buffer. The mixture was transferred into a 0.5-ml microcentrifugation tube, 0.5 unit of Taq DNA polymerase (Perkin-Elmer Cetus) was added thereto, and 10 .mu.l of mineral oil was layered over the mixture. The reaction was carried out using the DNA Thermal Cycler (Perkin-Elmer Cetus) for 40 cycles with the cycle profile consisting of 30 seconds at 93.degree. C. and 1 minute at 55.degree. C. According to the methods described in the book by Maniatis et al., the PCR products were subjected to 10% polyacrylamide gel electrophoresis, and DNA bands were stained with ethidium bromide and examined under UV light.
As a result, in the SSP-PCR using J14 primer, a DNA band of about 280 bp was obtained when one of the six types of cDNAs obtained from Falcon Blue, Purple Joy, and four delphinidin-type backcrossed plants was used as the template. On the other hand, the band was not detected when one of the four types of cDNAs obtained from Falcon Red, Falcon Salmon, and two cyanidin-type backcrossed plants was used as the template. That is, it was demonstrated that the presence/absence of the SSP-PCR products of about 280 bp was genetically linked to the presence/absence of said enzyme activity. It was strongly suggested that the core sequence shown by SEQ ID NO: 43 was a part of the DNA sequence encoding the polypeptide which had said enzyme activity.
