CCR1 — Camelina sativa

Summary

CsCCR2 (CSA09G094110, symbol CCR1) on Camelina sativa chromosome 9 encodes a cinnamoyl-CoA reductase (EC 1.2.1.44) with flavanone 4-reductase and dihydroflavanol 4-reductase activities, belonging to the NAD(P)-binding domain superfamily. The gene is associated with lignin and phenylpropanoid biosynthesis, anthocyanin metabolism, and green leaf volatile production. It is linked to lignin content, cold and drought stress responses, immunity, chloroplast and etioplast development, plastid biogenesis, leaf virescence, and coumarin accumulation. Additional associations include downregulation of circadian rhythm, non-homologous end joining DNA repair, and defense responses. The protein localizes to the cytoplasm and participates in the conversion of feruloyl-CoA and 4-coumaroyl-CoA to their respective aldehydes. Related genes in other species connect the family to disease resistance, seed coat color, and plastid development traits.
