ABSTRACT:
The present invention provides a sweet sorghum plant characterized by altered lignin content and/or altered lignin composition compared to a wild plant and this is achieved by manipulating the expression of caffeoylCoA-O-methyltransferae (CCoAOMT) in particular and optionally caffeic acid-O-methyltranferase (COMT) in sweet sorghum by incorporation of a construct comprising an isolated DNA sequence represented by SEQ ID NO 2 and optionally SEQ ID NO 1.
