MYB2 — Brassica oleracea var. botrytis

Summary

BoMYB2 (MYB2) on cauliflower chromosome 4 encodes a DNA-binding transcription factor with a Myb domain, belonging to the EOBI/EOBII-like plant family. It is annotated to bind RNA polymerase II cis-regulatory regions, calmodulin, and kinases, and localises to the nucleus and plant-type cell wall. The gene is associated with the regulation of phenylpropanoid, shikimate, indole glucosinolate, anthocyanin, and flavonoid metabolism, as well as secondary cell wall biogenesis, stomatal complex development, floral organ senescence, pigmentation, desiccation response, and defence responses to insects and viruses. It has been linked to traits including shoot elongation under submergence, phosphorus response, branch angle, seed protein content, aphid and insect damage response, anthocyanin content, salt tolerance, abscisic acid sensitivity, flowering time, and disease tolerance. Studies of related genes in other species connect the family to drought tolerance, hypoxia response, phosphate starvation response, and resistance to fungal pathogens and herbivory.
