CCR — Brachypodium distachyon

Summary

BdCCR (BRADI_4G08647V3) on chromosome 4 of Brachypodium distachyon encodes a cinnamoyl-CoA reductase (EC 1.2.1.44) with NAD(P)-binding and epimerase/dehydratase domains, and 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 production, circadian rhythm, defense responses and cold response. It is linked to traits including grain filling period, photosynthetic rate, IAA content, lignin content, saccharification yield, plant growth, senescence, male sterility, secondary cell wall morphology, and cold, drought and salt stress. Studies of related genes in other species connect the family to cell wall degradability and structure, lignin accumulation, abiotic and biotic stress tolerance, and yield.
