CCR — Brachypodium distachyon

Summary

BdCCR (BRADI_1G47300V3) on chromosome 1 of Brachypodium distachyon encodes a cinnamoyl-CoA reductase (EC 1.2.1.44) with NAD(P)-binding and epimerase/dehydratase domains, and exhibits oxidoreductase, flavanone 4-reductase and dihydroflavanol 4-reductase activities. The gene is associated with lignin, anthocyanin and phenylpropanoid biosynthesis, as well as green leaf volatile biosynthesis, circadian rhythm regulation, defense response and cold response. It is linked to grain filling period, photosynthetic rate and IAA content. Associations include lignin content, saccharification yield, secondary cell wall morphology, coumarin and sinapoyl malate accumulation, plant growth, senescence, male sterility, salt tolerance, and etioplast, chloroplast and plastid biogenesis. Studies of related genes in other species connect the family to cell wall degradability, disease resistance, stem physical properties and drought tolerance, as well as lignin accumulation, abiotic and biotic stress responses, and yield.
