MYBL2 — Brassica oleracea

Summary

BoMYBL2 (BOLC102_C06P050020.1_BOLC102_V1) on cabbage chromosome 6 encodes a Myb-family transcription regulator with DNA-binding, chromatin-binding, protein dimerization, kinase, and steroid-binding activities. It is associated with proanthocyanidin and carotenoid biosynthesis, anthocyanin regulation, chlorophyll metabolism, brassinosteroid signalling inhibition, and UV protection. The gene is linked to plant epidermal cell fate specification, root hair differentiation, anther wall tapetum cell differentiation, pollen exine formation, and quiescent center organization. Traits connected to BoMYBL2 include flavonoid content, leaf color and trichome density, silique morphology, stamen length, shoot branching, root epidermal cell length, seedling hypocotyl length, stem elongation, nitrate uptake, photoperiod-sensitive flowering time, temperature stress response, and auxin and ethylene sensitivity. Studies of related genes in other species link the family to trichome development, anthocyanin accumulation, root hair differentiation, and insect resistance.
