FUS3 — Brassica oleracea var. botrytis

Summary

BoFUS3, on cauliflower chromosome 7, encodes a LEC2-like transcription factor with a B3 DNA-binding domain and possesses DNA-binding transcription factor activity, protein kinase activity, and supercoiled DNA binding. It is associated with the regulation of embryonic development, seed dormancy, fruit development, and vegetative phase change, and is linked to positive regulation of abscisic acid anabolism and negative regulation of gibberellin biosynthesis. The gene has been connected to seed yield, drought tolerance, submergence tolerance, high temperature stress response, leaf curling, stem senescence, and root development traits. It is also associated with vivipary, embryo maturation, seed storage reserve accumulation, oil accumulation, and flowering time. Studies of related genes in other species link the family to somatic embryogenesis, seed maturation, triacylglycerol accumulation, and developmental timing.
