CCR1 — Brassica napus

Summary

BnCCR1 (DARMORV10_C05P14170.1) on chromosome C05 of oilseed rape encodes a protein with NAD(P)-binding and epimerase/dehydratase domains and exhibits cinnamoyl-CoA reductase, flavanone 4-reductase, and dihydroflavanol 4-reductase activities. The gene is associated with lignin and phenylpropanoid biosynthesis, anthocyanin and flavonoid metabolism, pigmentation, defense response, cold response, circadian rhythm, and signal transduction. It is linked to seed coat color, protein content, seed dormancy, male sterility, lignin content and lignification, coumarin and sinapoyl malate accumulation, secondary cell wall morphology, salt tolerance, plant height, saccharification yield, senescence, and plant growth. The encoded protein localizes to the cytoplasm. Studies of related genes in other species link the family to cell wall degradability, stem physical properties, and collapsed xylem with dwarfism and reduced fertility.
