  • DWF4 polynucleotides, polypeptides and uses thereof
    Patent number: 7935532
    Abstract: The present invention relates to novel, polynucleotides isolated from dwarf plants. The dwf4 polynucleotides that encode all, or a portion of, a DWF4 polypeptide, a cytochrome P450 enzyme that mediates multiple steps in synthesis of brassinosteriods. The present invention also relates to isolated polynucleotides that encode regulatory regions of dwf4. Uses of the dwf4 polypeptides and polynucleotides are also disclosed.
