FUS3 — Brassica napus

Summary

BnFUS3 (FUS3) on chromosome C07 of oilseed rape encodes a B3 DNA-binding domain transcription factor of the LEC2-like family. It is associated with DNA binding, transcription cis-regulatory region binding, and protein kinase activity, and localises to the nucleus and cytosol. The gene is linked to the regulation of embryonic development, negative regulation of gibberellin biosynthesis, positive regulation of abscisic acid anabolism, and proanthocyanidin, triglyceride, starch, and fatty acid metabolism. It has been connected to seed colour, seed yield, germination rate, drought tolerance, submergence tolerance, high temperature stress response, oxidative stress response, flowering time, leaf and root development traits, and plant morphology. Studies of related genes in other species link the family to seed maturation, somatic embryogenesis, triacylglycerol accumulation, and developmental timing.
