CCR1 (TRAESCS5A02G061600) — triticum aestivum

Summary

TRAESCS5A02G061600 (symbol CCR1, also known as CCR2) on bread wheat chromosome 5A encodes a protein with NAD(P)-binding and epimerase/dehydratase domains that exhibits cinnamoyl-CoA reductase, flavanone 4-reductase and dihydroflavanol 4-reductase activities. This gene is associated with lignin, flavonoid, anthocyanin and phenylpropanoid biosynthesis, as well as green leaf volatile production, sucrose metabolism, circadian rhythm regulation, cold and defense responses. It has been linked to drought tolerance in wheat and to traits including grain weight, grain filling period, plant height, shoot fresh weight, root number and length, photosynthetic rate, stripe rust, auxin content, lignin content, saccharification yield, male sterility, senescence, coumarin and sinapoyl malate accumulation, and abiotic and biotic stress responses. Studies of related genes in other species connect the family to cell wall structure, disease resistance and stem physical properties.
