CCR — Brachypodium distachyon

Summary

BdCCR (BRADI_3G54971V3) on chromosome 3 of Brachypodium distachyon encodes a cinnamoyl-CoA reductase with oxidoreductase activity acting on CH-OH groups using NAD or NADP, and also exhibits flavanone 4-reductase and dihydroflavanol 4-reductase activities. The gene is associated with lignin and phenylpropanoid biosynthesis, anthocyanin anabolism, green leaf volatile biosynthetic process, defense response, response to cold, and downregulation of circadian rhythm. It is linked to grain filling period, photosynthetic rate, IAA content, and phenotypes including lignin content, saccharification yield, secondary cell wall morphology, plant growth, senescence, male sterility, coumarin and sinapoyl malate accumulation, etioplast and chloroplast development, leaf virescence, plastid biogenesis, cold and drought stress responses, salt tolerance, and immunity. Studies of related genes in other species connect the CCR family to lignin accumulation, cell wall degradability, drought tolerance, disease resistance, and yield-related traits.
