MYB2 — Brassica oleracea

Summary

BoMYB2 (BOLC102_C04P077020.1) on cabbage chromosome 4 encodes a DNA-binding transcription factor of the MYB family, containing a Myb domain and SANT/Myb domain, and is annotated with RNA polymerase II cis-regulatory region sequence-specific DNA binding, calmodulin binding, and kinase binding activities. The gene is associated with regulation of anthocyanin and flavonoid biosynthesis, pigmentation, phenylpropanoid metabolism, indole glucosinolate anabolism, and shikimate metabolism. It is linked to responses to desiccation, oxidative stress, salt, drought, and abscisic acid, as well as defense responses to insects and viruses, floral organ senescence, stomatal complex development, and green leaf volatile biosynthesis. Associations with agronomic traits include seed protein content, shoot growth angle, branch angle, root architecture, flowering time, disease tolerance, and salt tolerance. Studies of related genes in other species link the family to drought tolerance, hypoxia response, secondary cell wall thickening, anther dehiscence, and phosphate starvation response.
