CCR — Sorghum bicolor

Summary

SORBI_3007G141200 (SbCCR) encodes a cinnamoyl-CoA reductase (EC 1.2.1.44) with oxidoreductase activity acting on CH-OH groups, and also exhibits flavanone 4-reductase and dihydroflavonol 4-reductase activities. The gene is associated with lignin, phenylpropanoid, anthocyanin, starch, and sucrose metabolism, as well as green leaf volatile biosynthesis, circadian rhythm, defense response, and cold response. SbCCR is linked to photosynthetic rate, grain filling period, and IAA content. Associations include lignin content, saccharification yield, secondary cell wall morphology, coumarin accumulation, plant growth, male sterility, senescence, and responses to 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, and traits such as grain yield, biomass yield, stem strength, and brittle culm.
