FUS3 — Brassica napus

Summary

BnFUS3 (FUS3) on chromosome C02 of oilseed rape encodes a B3 DNA-binding domain transcription factor of the LEC2-like family. The gene product exhibits DNA binding, transcription cis-regulatory region binding, protein kinase activity, and zinc binding. BnFUS3 is associated with negative regulation of gibberellin biosynthesis, positive regulation of abscisic acid anabolism, proanthocyanidin and triglyceride anabolism, lipogenesis, fatty acid and starch metabolism, and regulation of embryonic development. It has been linked to numerous agronomic traits including seed color, seed yield, protein content, germination rate, drought tolerance, submergence tolerance, high temperature stress response, oxidative stress response, flowering time, leaf senescence, root development, and plant morphology. Additional associations include seed dormancy, oil accumulation, storage protein accumulation, seed size, vivipary, and heat stress tolerance. The protein localizes to the nucleus, cytosol, and Golgi complex.
