FUS3 — Brassica napus

Summary

BnFUS3 (FUS3) on chromosome A06 of oilseed rape encodes a LEC2-like protein with a B3 DNA-binding domain and possesses DNA binding, transcription factor, kinase, and protein binding activities. It is associated with negative regulation of gibberellin biosynthetic process, positive regulation of abscisic acid anabolism, proanthocyanidin anabolism, triglyceride anabolism, lipogenesis, fatty acid metabolism, starch metabolism, regulation of embryonic development, and xylem development. The gene is linked to numerous seed and agronomic traits, including seed color, yield, protein content, oil accumulation, dormancy, germination rate, and storage reserve accumulation, as well as stress responses such as drought tolerance, submergence tolerance, high temperature stress response, and oxidative stress response. It is also linked to flowering time, vegetative phase change, leaf and root development traits, and abscisic acid sensitivity. Studies of related genes in other species link the family to somatic embryogenesis, seed maturation, and triacylglycerol accumulation.
