CCR — Brachypodium distachyon

Summary

BdCCR (BRADI_3G19670V3) on chromosome 3 of Brachypodium distachyon encodes a cinnamoyl-CoA reductase, an oxidoreductase with NAD(P)-binding and epimerase/dehydratase domains that also exhibits flavanone 4-reductase and dihydroflavanol 4-reductase activities. The gene is associated with lignin, phenylpropanoid, flavonoid, and anthocyanin biosynthesis, as well as green leaf volatile biosynthesis, defense response, cold response, and downregulation of circadian rhythm. It is linked to traits including photosynthetic rate, grain filling period, and IAA content, and to phenotypes such as lignin content, saccharification yield, secondary cell wall morphology, coumarin and sinapoyl malate accumulation, plant growth, senescence, male sterility, and responses to cold, drought, and salt stress. Studies of related genes in other species link the family to cell wall degradability and structure, lignin accumulation, abiotic and biotic stress tolerance, and yield.
