General Information

General Information Comment Organism
physiological function O-methyltransferase COMT6-deficient mutant Bd5139 displays a moderately altered lignification in mature stems. The COMT6 gene is also expressed in grains, and the alterations of Bd5139 grain lignins mirror nicely those evidenced in stem lignins. The Bd5139 grains display similar size and composition to the control. Introducing the mutated gene into the COMT1-deficient Arabidopsis thaliana mutant demonstrates that the mutated COMT6 protein is still functional. The moderate down-regulation of lignin-related COMT enzyme reduces the straw recalcitrance to saccharification, without compromising the vegetative or reproductive development of the plant Brachypodium distachyon
