WRI — Brassica napus

Summary

BnWRI (DARMORV10_C08P29550.1) on chromosome C08 of oilseed rape encodes a transcription factor containing an AP2/ERF domain that binds DNA and zinc, and is annotated with kinase and identical protein binding activities. The gene is associated with the regulation of seed development, lipid and fatty acid homeostasis, malonyl-CoA and pyruvate metabolism, glycolytic process regulation, and diacylglycerol anabolism. It is linked to seed oil content and accumulation, triacylglycerol biosynthesis, fatty acid synthesis, seed weight and size, embryo development, seed maturation, and abscission. Associations also include grain yield, starch and sugar content, chlorophyll content, root and hypocotyl morphology, flowering time, auxin and abscisic acid sensitivity, and responses to light and UV-B. The gene is linked to the BPM and CUL3 proteins. Studies of related genes in other species connect the family to seed oil biosynthesis, fatty acid composition, and lipid production.
