Title: Methods for increasing the yield of fermentable sugars from plant stover

Abstract

Methods for increasing yield of fermentable sugars from plant stover are provided. The methods include using plants homozygous for two brown midrib mutations, bm1 and bm3. The methods also include using plants homozygous for a mutation in a gene that results in reduced cinnamyl alcohol dehydrogenase activity, and a mutation in a gene that results in reduced 5-hydroxyconiferaldehyde/5-hydroxyconiferyl alcohol O-methyltransferase activity. The methods also include using transgenic plants that have reduced cinnamyl alcohol dehydrogenase activity and reduced 5-hydroxyconiferaldehyde/5-hydroxyconiferyl alcohol O-methyltransferase activity in comparison with wild-type plants.
