- 4. An isolated polynucleotide having a sequence selected from
(a) sequences complementary to any of the sequences in claim 2;(b) sequences that are reverse complements to any of the sequences in claim 2; and (c) sequences comprising at least 20 contiguous bases, which hybridizes to any of the polynucleotides of (a) or (b).
- 5. The isolated nucleic molecule of claim 1, wherein said polynucleotide confers xylem-preferred gene expression in a plant cell.
- 6. The isolated nucleic molecule of claim 1, wherein said polynucleotide is capable of upregulating or downregulating the expression of an operably-linked gene in a plant cell.
- 7. A plant cell comprising (a) at least one polynucleotide sequence that has the sequence of any one of SEQ ID NO: 1-85; and (b) a desired gene, wherein said polynucleotide and said desired gene are operably linked.
- 8. The plant cell of claim 7, wherein said desired gene encodes a polypeptide or protein.
- 9. The plant cell of claim 8, wherein said protein is an enzyme involved in the biosynthesis of cell walls.
- 10. The plant cell of claim 8, wherein said protein is an enzyme involved in lignin biosynthesis.
- 11. The plant cell of claim 7, wherein said desired gene produces an RNA transcript.
- 12. The plant cell of claim 11, wherein said RNA transcript has an antisense sequence of a gene that is endogenous to a plant cell.
- 13. The plant cell of claim 12, wherein said RNA transcript induces RNA interference of a gene that is normally expressed in a plant cell.
- 14. A plant comprising the plant cell of claim 7.
- 15. The plant of claim 14, wherein said plant is selected from angiosperms and gymnosperms.
- 16. A method for regulating the lignin content of a plant, comprising cultivating the plant of claim 14.
- 17. A method for regulating cell wall development in a plant, comprising cultivating the plant of claim 14.
- 18. A transgenic plant comprising a polynucleotide sequence selected from any one of SEQ ID NO: 1-85 and functional variants thereof.
- 19. A method for obtaining wood, comprising (a) introducing into a plant cell of a woody plant a DNA construct comprising (i) a promoter having the sequence of any one of SEQ ID NOS: 1 to 85 or functional variants thereof and (ii) and a desired nucleic acid, wherein said promoter regulates the expression of said desired nucleic acid; (b) culturing said transformed plant cell under conditions that promote growth of a plant; and (c) obtaining wood from said plant.
- 20. The method of claim 19, wherein said woody plant is selected from a species of Eucalyptus or Pinus.
