Fig. 1From: Suppression of CINNAMOYL-CoA REDUCTASE increases the level of monolignol ferulates incorporated into maize ligninsAn abbreviated version of the lignin biosynthetic pathway highlighting the effects of the ccr1 mutation. The mutated CCR1 gene results in reduced CCR1 transcript, and presumably less CCR1 enzyme, and a pool of feruloyl-CoA (FA reservoir). The conjugates formed between the monolignols and feruloyl-CoA by ZmFMT are incorporated into the lignin polymer, generating a zip-lignin in which the ester bonds in the backbone are readily cleaved by baseBack to article page
