MYB2 — Brassica oleracea var. botrytis

Summary

BoMYB2 (MYB2) on cauliflower chromosome CBFFJS010000040.1 encodes a DNA-binding transcription factor with calmodulin- and kinase-binding activity, belonging to the Myb domain and EOBI/EOBII-like plant protein families. It is associated with regulation of phenylpropanoid, flavonoid, anthocyanin, indole glucosinolate and shikimate metabolism, as well as cell wall organization, pigmentation, stomatal development, floral organ senescence, defense responses to insects and viruses, and response to desiccation. The gene is linked to numerous agronomic traits including anthocyanin content, seed protein content, flowering time, branch angle, shoot elongation under submergence, root architecture, salt tolerance, drought response, abscisic acid sensitivity, aphid and insect damage response, disease tolerance, leaf senescence, and oxidative stress response. Studies of related genes in other species connect the family to drought tolerance, hypoxia response, phosphate starvation response, secondary cell wall thickening, anther dehiscence, and resistance to fungal pathogens and herbivory.
