CCR2 — Brassica napus

Summary

BnCCR2 (DARMORV10_A07P44860.1) on chromosome A07 of oilseed rape encodes a protein with cinnamoyl-CoA reductase activity, flavanone 4-reductase activity, dihydroflavanol 4-reductase activity, and oxidoreductase activity, belonging to the NAD(P)-binding domain superfamily. This gene is associated with lignin, phenylpropanoid, flavonoid, anthocyanin, and proanthocyanidin anabolism, as well as xylem development, seed development, flower formation, and chlorophyll anabolism. It has been linked to seed coat color, lignin content, coumarin accumulation, and responses to cold, drought, and immunity. Additional associations include chloroplast and etioplast development, plastid biogenesis, leaf virescence, circadian rhythm, and protein breakdown. Studies of related genes in other species connect the family to disease resistance, while sequence similarity links extend to plastid development, lignin biosynthesis, and drought tolerance traits.
