Patent ID: 7994398

Claim:
A recombinant expression cassette, comprising an isolated polynucleotide selected from the group consisting of: a. a polynucleotide having at least 96% identity, as determined by the GAP algorithm under default parameters, to the full length sequence of a polynucleotide consisting of SEQ ID NO:1, wherein the polynucleotide encodes a polypeptide that functions as a modifier of secondary cell wall development; b. a polynucleotide encoding a polypeptide consisting of SEQ ID NO:2; and c. a polynucleotide consisting of SEQ ID NO: 1; and d. a polynucleotide which is fully complementary to the polynucleotide of (a), (b) or (c), wherein the polynucleotide is operably linked, in sense or anti-sense orientation, to a promoter.
