Patent ID: 7709701

Claim:
A transgenic plant transformed with a first selected DNA encoding TT2 and a second selected DNA encoding a BAN polypeptide with anthocyanidin reductase activity, wherein the transgenic plant expresses the first selected DNA and the second selected DNA; and the transgenic plant exhibits increased condensed tannin biosynthesis relative to a second plant that differs from the transgenic plant only in that the first selected DNA and the second selected DNA are absent, and wherein the first selected DNA encoding TT2 comprises a sequence selected from the group consisting of: a) a nucleic acid sequence encoding the polypeptide of SEQ ID NO:76; b) a nucleic acid sequence comprising the sequence of SEQ ID NO:75; c) a nucleic acid sequence having at least 95% sequence identity to the nucleic acid sequence of SEQ ID NO:75 and which encodes a TT2 transcription factor wherein the TT2 transcription factor confers increased condensed tannin biosynthesis in the transgenic plant when the second selected DNA encoding a BAN polypeptide is also expressed in the plant; and d) a nucleic acid sequence encoding a polypeptide sequence having at least 95% sequence identity to SEQ ID NO:76 and encodes a TT2 transcription factor wherein the TT2 transcription factor confers increased condensed tannin biosynthesis in the transgenic plant when the second selected DNA encoding a BAN polypeptide is also expressed in the plant.
