CCR — Sorghum bicolor

Summary

SORBI_3010G066000 (SbCCR) on sorghum chromosome 10 encodes a cinnamoyl-CoA reductase (EC 1.2.1.44), a NAD(P)-dependent enzyme with cinnamoyl-CoA reductase, flavanone 4-reductase and dihydroflavanol 4-reductase activities. The gene is associated with lignin, anthocyanin and phenylpropanoid biosynthesis, as well as starch and sucrose metabolism, primary metabolism, green leaf volatile biosynthesis, circadian rhythm, defense response and cold response. It has been linked to grain filling period, photosynthetic rate, IAA content, lignin content, saccharification yield, secondary cell wall morphology, plant growth, leaf virescence, etioplast and chloroplast development, male sterility, senescence, coumarin and sinapoyl malate accumulation, and cold, drought and salt stress. Studies of related genes in other species connect the CCR family to cell wall degradability, disease resistance, stem physical properties, grain yield, biomass yield and abiotic stress tolerance.
