This application claims priority from Japanese Patent Application No. 2020-136913 filed on Aug. 14, 2020. The entire disclosure of this Japanese patent application is incorporated herein by reference.
The present invention relates to a broccoli plant.
Broccoli plants are cultivated in winter, harvesting from December to January. However, in winter cultivation, broccoli plants tend to grow slowly, and anthocyanin coloration often occurs. Broccoli plants colored with anthocyanin have a problem of low merchantability.
Therefore, there is a need for broccoli plants with superior characteristics.
With the foregoing in mind, it is one objective of the present invention to provide a new broccoli plant.
In order to achieve the above objective, the present invention provides a broccoli plant including a broccoli plant identified by Accession No. FERM BP-22393.
The present invention also provides a method for producing a broccoli plant, including the step of self-crossing the broccoli plant according to the present invention.
The present invention also provides a method for producing a broccoli plant, including the step of crossing the broccoli plant according to the present invention with another broccoli plant.
According to the present invention, a new broccoli plant can be provided.
<Broccoli Plant>
The broccoli plant of the present invention includes a broccoli plant identified by Accession No. FERM BP-22393 or a progeny line thereof. The broccoli plant of the present invention is characterized in that it includes a broccoli plant identified by Accession No. FERM BP-22393 or a progeny line thereof, and other configurations or conditions are not particularly limited.
In the present invention, a “broccoli plant” is a plant classified into Brassica oleracea var italica of Brassica oleracea of Brassica. Examples of the broccoli plant include Brassica oleracea var. italica (Brassica oleracea L. convar. Botrytis (L.) Alef. var. italica) and Brassica oleracea var. cymosa Duch. (Brassica oleracea L. convar. botrytis (L.) Alef var. cymosa Duch.). The broccoli plant may be a hybrid with a related species or a wild species, for example.
In the present invention, a “broccoli plant for cultivation,” a “broccoli variety for cultivation,” or a “broccoli for cultivation” is a broccoli plant or a variety thereof, a breeding line, or a cultivar that is cultivated by humans and is excellent in cultivation. The “broccoli plant for cultivation,” the “broccoli variety for cultivation,” or the “broccoli for cultivation” may be a hybrid thereof, a hybrid with another broccoli variant, or a hybrid with another Brassica oleracea.
The term “plant,” as used in the present invention, may refer to either a plant individual representing the whole plant or a part of the plant individual (plant part). Examples of the “plant” include plant cells, plant protoplasts, plant cell cultures or tissue cultures capable of regenerating plants, plant calli, plant clumps, plant cells isolated from plants or plant parts, leaves, pollens, embryos, cotyledons, hypocotyls, roots, root tips (tips of roots), anthers, pistils, flowers, ovaries, ovules, seeds, fruits, stems, and seedlings. The part of the plant individual may be any of organs, tissues, cells, and propagules, for example. Examples of the organs include petals, corollas, flowers, leaves, seeds, fruits, stems, and roots. The tissue is a part of the organ, for example. Specific examples of the part of the plant individual include microspores, flowers, flower buds, pistils, anthers, pollens, ovaries, embryos, ovules, hypocotyls, embryonic sacs, egg cells, cuttings, roots, root tips, trunks, stems, leaves, pedicles, leaf marrow, cotyledons, cells, meristematic cells, protoplasts, and seeds. The pollens may be mature pollens or immature pollens. The part of the plant individual can be, for example, derived from a plant at any growth stage, and may be derived from, for example, a pre-rooting individual, a post-rooting individual, a seedling, a cutting, or a mature individual, and the like. The part of the plant body may be one type of organ, tissue, and/or cell, or two or more types of organs, tissues, and/or cells, for example.

The main characteristics are preferably characteristics of Characteristic Nos. 9, 13, 21, and 36 in Tables 1A and 1B, i.e., the following characteristics of (1) to (3) and (9) and self-incompatibility. The plants having essentially all physiological and morphological characteristics of the deposited line may be, for example, plants having the same characteristic as the deposited line, except for 10 or less, 9 or less, 8 or less, 7 or less, 6 or less, 5 or less, 4 or less, 3 or less, 2 or less, or 1 characteristic, i.e., 10 or less, 9 or less, 8 or less, 7 or less, 6 or less, 5 or less, 4 or less, 3 or less, 2 or less, or 1 characteristic may differ from the deposited line. The “characteristic different from the deposited line” may be a main characteristic of the deposited line or a characteristic other than the main characteristic of the deposited line, and is preferably a characteristic other than the main characteristic of the deposited line. The “characteristic different from the deposited line” can be made, for example, by the introduction of a characteristic and/or introduction of a gene, which will be described below. In the plants having essentially all the physiological and morphological characteristics of the deposited line, all the characteristics of Characteristic Nos. 1 to 21, 23 to 32, 34 to 38, and 40 to 43 and self-incompatibility may be the same as the deposited line.

The deposited lines have, for example, the single nucleotide polymorphisms (SNPs) described in Tables 2A through 2U below. In Tables 2A through 2U, the base [N1/N2] in parentheses denotes a single base polymorphism in which N1 is a base in a dataset (Brassica oleracea L.: genome base sequence of TO1000) registered in NCBI with RefSeq assembly accession: GCF_000695525.1 (https: //www.ncbi.nlm.nih.gov/assembly/GCF_000695525.1/) and N2 is a base other than the base in the dataset. For the analysis of the data set, reference can be made to Reference 2 below, for example.
<Progeny Line>
The broccoli plant of the present invention may be a progeny line of a deposited line. The progeny line may be a plant individual of a progeny line, a part of a plant individual of a progeny line, or a seed of a progeny line.
In the present invention, the “progeny line” or the “progeny broccoli plant” (hereinafter collectively referred to as the “progeny line”) is a plant obtained from a broccoli plant of the deposited line or the progeny line thereof. In the present invention, the progeny line may be a plant obtained from crossing the deposited line with another deposited line or another broccoli plant, or by crossing the deposited line with a wild broccoli plant. The progeny line may be obtained, obtainable, or derived directly or indirectly through self-crossing and/or cross-pollination of the deposited line or a progeny line thereof. Also, the progeny line may be derived from a parental line obtained from the deposited line using traditional breeding methods such as self-crossing and/or cross-pollination. Examples of the progeny line include self-crossing progeny lines and first-generation hybrids F1 (hybrid first-generation line, F1 hybrid). In obtaining the progeny line, the deposited line may be used as a female parent, a male parent, or both parents.
The term “crossing” as used in the present invention refers to the crossing of two parent lines. The crossing may be “cross-pollination” or “self-pollination.” Cross-pollination refers to fertilization by the binding of two gametes derived from different plants. Self-pollination means that pollens migrate from the anther to the stigma of the same plant. Self-pollination can also be referred to as self-crossing, for example. The crossing may include backcrossing, which is one of the traditional breeding methods.
The “backcrossing” is one of the traditional breeding techniques in which a breeder repeatedly backcrosses a progeny line of the hybrid to one of the parental lines and introduces a characteristic into a plant or a variety. A plant including the characteristic to be introduced may be referred to as a donor plant, for example. A plant into which the characteristic is introduced may be referred to as a recurrent parent, for example. The backcrossing can be performed by crossing a donor plant with a recurrent parent, thereby obtaining a first-generation hybrid F1 (hybrid first-generation line, F1 hybrid). The progeny line having a characteristic is then crossed with a recurrent parent. Then, by backcrossing and/or self-crossing several generations, the characteristic of the donor plant can be introduced into the recurrent parent.
In the present invention, the progeny line may be regenerated from a cell culture or a tissue culture derived from the deposited line, a protoplast, or a part of a plant individual; may be obtained by self-crossing the deposited line; or may be obtained by producing seeds from the plant individual of the deposited line.
The term “regeneration,” as used in the present invention, refers to the development or vegetative propagation of a plant from a cell culture, a tissue culture, or a protoplast.
The “tissue culture” or “cell culture” may be a composition including the same or different types of isolated cells or may be a collection of cells that are organized into parts of a plant. Tissue cultures of various tissues of broccoli plants and methods for regenerating plants from the tissue cultures are well known, and reference can be made to References 3 to 5 below, for example.
The progeny lines may have desired characteristics. The progeny lines may have “essentially all physiological and morphological characteristics of the deposited line” when they are cultivated in the same cultivation conditions, for example. Specifically, the progeny line may have a common characteristic with the deposited line. As a specific example, 1 or more, 2 or more, 3 or more, 4 or more, 5 or more, 6 or more, 7 or more, 8 or more, 9 or more, 10 or more, 11 or more, 12 or more, or 13 or more characteristics of the progeny line match the characteristics of the deposited line. The progeny line may be a plant having the main characteristic of the deposited line. The main characteristics are characteristics of Characteristic Nos. 9, 13, 21, and 36 in Tables 1A and 1B, i.e., the characteristics of (1) to (3) and (9). The progeny lines may be, for example, plants having the same characteristic as the deposited line, except for 13 or less, 12 or less, 11 or less, 10 or less, 9 or less, 8 or less, 7 or less, 6 or less, 5 or less, 4 or less, 3 or less, 2 or less, or 1 characteristic, i.e., 13 or less, 12 or less, 11 or less, 10 or less, 9 or less, 8 or less, 7 or less, 6 or less, 5 or less, 4 or less, 3 or less, 2 or less, or 1 characteristic may differ from the deposited line. The “characteristic different from the deposited line” may be a main characteristic of the deposited line or a characteristic other than the main characteristic of the deposited line, and is preferably a characteristic other than the main characteristic of the deposited line. The “characteristic different from the deposited line” can be made, for example, by the introduction of a characteristic and/or introduction of a gene, which will be described below. In the progeny lines, all the characteristics of Characteristic Nos. 1 to 38 may be the same as the deposited line. Examples of the characteristic different from the deposited lines include diamondback moth (Plutella xylostella) insect resistance, fall armyworm (Spodoptera frugiperda) resistance, LSL (Long Shelf Life, stay green, ethylene insensitive), and characteristics of coloring green even under weak light (characteristics of coloring green even in hidden areas). Each characteristic can be introduced, for example, by crossing with a known plant having a locus associated with each characteristic.
The progeny line may include a cell containing at least one set of chromosomes derived from the deposited line. At least 6.25%, 12.5%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99% of allele of the progeny line may be derived from the deposited line. That is, the progeny line may have at least about 6.25%, 12.5%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99% genetic complement with the deposited line.
The “allele” is any one or more genes, and all of which are associated with a trait or characteristic of a broccoli plant. In a diploid cell or organism, a pair of alleles of a given gene occupy the corresponding locus on a pair of homologous chromosomes.
The genetic complement can be calculated, for example, by decoding a molecular marker or a base sequence, comparing it with a molecular marker or a base sequence of a Takii 12, and calculating a concordance rate. Examples of the molecular marker include SNP markers, amplified fragment length polymorphism (AFLP) markers, restriction fragment length polymorphism (RFLP) markers, microsatellite markers, sequence-characterized amplified region markers, and cleaved amplified polymorphic sequence (CAPS) markers. Methods for analyzing genomes using the molecular markers are well known and widely published (e.g., References 6 and 7 below). The base sequence can be decoded, for example, by extracting a chromosome from the progeny line and sequencing the chromosome. The proportion of allele derived from the deposited line and the proportion of genetic complement may be estimated, for example, by the number of times of crossing. In this case, the proportion can be estimated from the number of times of crossing from the deposited line. As a specific example, when the number of times of crossing from the deposited line is n, the proportion can be estimated to be, for example, (½)n×100%.
Preferably, the proportion of allele derived from the deposited line and the proportion of genetic complement is, for example, an average value of the proportion of a plurality of progeny lines. The “plurality” here, for example, is the number of individuals capable of subjecting statistical examination, and, as a specific example, is 200 individuals or more, and preferably 200 to 1,000 individuals.
The progeny line may have an SNP derived from the deposited line. The SNPs of the deposited line are the SNPs shown in Tables 2A through 2U. At least 6.25%, 12.5%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99% of the SNPs of the progeny line may be derived from the deposited line, for example. That is, at least about 6.25%, 12.5%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99% of the SNPs of the progeny line may match the SNPs of the deposited line. In the present invention, if 50%, 55%, 60%, 65%, 70%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, or 99% or more of the SNPs of a target broccoli plant match the SNPs of the deposited line, for example, the target broccoli plant can be determined (discriminated, estimated, appraised, or distinguished) to be a progeny line of the deposited line. For example, the progeny line preferably has at least one SNP selected from the group consisting of SNP7, SNP8, SNP20, SNP21, SNP75, SNP78, SNP81, SNP84, SNP90, SNP142, SNP165, and SNP177 among the SNPs of the deposited line, and more preferably has at least one SNP selected from the group consisting of SNP78, SNP81, and SNP142 among the SNPs of the deposited line.
The progeny line may have, for example, a mutation or transgene. In this case, the progeny line has, for example, one or more characteristics modified. The progeny line can be produced, for example, by transferring a mutation or a transgene into the deposited line or a progeny line thereof. The mutations may be introduced artificially or may be introduced naturally. The mutation may be, for example, a chemical-induced mutation or a radiation-induced mutation. Also, the mutation may be introduced, for example, by a molecular biological procedure or a genome-editing technique (e.g., Reference 8 below). As to the transgene, a method using Agrobacterium tumefaciens can be given.
Examples of the one or more characteristics include diamondback moth insect resistance, fall armyworm resistance, LSL (stay green, ethylene insensitive), and characteristics of coloring green even under weak light (characteristics of coloring green even in hidden areas).
The “transgene” refers to a desired gene introduced into the genome of a plant, e.g., by a genetic engineering procedure or a traditional breeding method. The transgenes may be derived from the same species or from different species, for example. The transgene may be a gene having the same base sequence as or a different base sequence from the species from which it is derived, for example. In the latter case, a different base sequence can be prepared, for example, by performing codon optimization, the addition of a transcription control factor such as a promoter, or the like, to the same base sequence. The transgene may have a translated region and an untranslated region.
<Haploid Plant and Doubled Haploid Plant>
The broccoli plant of the present invention may be a haploid plant and/or a doubled haploid plant that is obtained, obtainable, or induced from the deposited line. The haploid plant and/or the doubled haploid plant of the deposited line may be used in a method for producing a parent line of the deposited line. In one embodiment, the present invention may provide a plant of a haploid plant and/or a doubled haploid plant, a plant part of a haploid plant and/or a doubled haploid plant, or a seed of a haploid plant and/or a doubled haploid plant.
The doubled haploid plants can be produced by doubling chromosomes in haploid plants or cells (e.g., Reference 9 below). As a specific example, haploid pollens are cultured under predetermined conditions to form 1n chromosome plantlets. The chromosomes are then doubled by treating plantlets with chemicals such as colchicine, for example. Thus, the cells of the plantlets have chromosomes of 2n (doubled haploids). Then, by growing the plantlets after the treatment, it is possible to obtain the doubled haploid plants and progeny lines.

It is to be noted, however, that the present invention is by no means limited to embodiments described in the following examples.
Broccoli plants of the deposited line were bred to examine their traits and characteristics and to examine polymorphisms possessed by the deposited line.
(1) Breeding of Deposited Line
In 2007, a broccoli line of stable cultivation with many leaves (made by TAKII & CO., LTD) was crossed with a broccoli line with relatively vigorous growth in a low-temperature period and no anthocyanin coloration (made by TAKII & CO., LTD) to obtain F1 generation. In 2008, the F1 generation was self-crossed to obtain F2 generation. The obtained F2 generation was selected by focusing attention on the stability of growth, the shape of the flower head, the color of the flower head, and the like, and the selected F2 generation was self-crossed. After that, selection and self-crossing were repeated in the same manner, thereby obtaining F7 generation. Since it was determined that the target characteristic was fixed, breeding was terminated at the F7 generation in 2013.
One hundred strains of F7 were seeded on Aug. 2, 2013 at the testing laboratory (Sato, Okubo-cho, Tahara-shi, Aichi Prefecture), and then cultivated to examine that there was no variation in characteristics in F7 and that the bred broccoli variety had uniformity and stability. Then, the F7 generation was self-crossed, and the seed of the F8 generation obtained was deposited in NITE-IPOD under Accession No. FERM BP-22393.
(2) Characteristics of Deposited Line
The traits and characteristics of F7 plant individuals were evaluated according to the Broccoli Variant Test Guideline published by the MAFF. The traits and characteristics of F7 plant individuals were also evaluated based on the criteria for Characteristic Nos. 40 to 42. The results are shown in Tables 3A through 3C below. It has been verified that the deposited lines also exhibit the same characteristics. Photographs of the F7 line at the time of harvest are shown in
(3) SNP Marker of Deposited Line
The SNPs described in Tables 2A through 2U were analyzed for the deposited lines and the commercial broccoli varieties described below. The results are shown in Tables 4A through 4G below. As shown in Tables 4A through 4G below, it was found that SNP7, SNP8, SNP20, SNP21, SNP75, SNP78, SNP81, SNP84, SNP90, SNP142, SNP165, and SNP177 are deposited line-specific SNPs and that the progeny line can be identified by combining one or more of these SNPs. It was verified that F7 has the same SNPs. In addition, in Tables 4A through 4G, A represents a homozygous type of SNP A, H represents a heterozygous type of SNP A and SNP B, B represents a homozygous type of SNP B, chr represents a chromosome number, and cM represents centimorgan.
