CCR — Brachypodium distachyon

Summary

BdCCR (BRADI_3G36887V3) on Brachypodium distachyon chromosome 3 encodes a cinnamoyl-CoA reductase (EC 1.2.1.44) with oxidoreductase activity acting on CH-OH groups using NAD or NADP, and also exhibits flavanone 4-reductase and dihydroflavanol 4-reductase activities. The protein contains NAD(P)-binding and epimerase/dehydratase domains. This gene is associated with lignin and phenylpropanoid biosynthesis, anthocyanin anabolism, green leaf volatile biosynthesis, defense response, cold response, and circadian rhythm. It is linked to grain filling period, photosynthetic rate, and IAA content. Phenotypic associations include lignin content and biosynthesis, saccharification yield, secondary cell wall morphology, plant growth, leaf virescence, etioplast and chloroplast development, male sterility, senescence, coumarin and sinapoyl malate accumulation, and responses to cold, drought, and salt stress. Studies of related genes in other species connect the family to cell wall degradability, disease resistance, stem strength, and biomass yield.
