PMG2 — Brassica oleracea

Summary

BoPMG2 (PMG2, also known as MYB29) on cabbage chromosome 3 encodes a transcription factor with a Myb DNA-binding domain, capable of sequence-specific DNA binding, chromatin binding, and transcription factor binding. It is associated with the regulation of glucosinolate biosynthetic processes, particularly aliphatic and indolic glucosinolate accumulation, and with cellular responses to sulfur starvation. The gene is associated with drought recovery, desiccation response, and abiotic stress tolerance, as well as insect defense and herbivory resistance. Additional associations include shoot elongation under submergence, phosphorus response, seed protein content, root architecture traits, flowering time, and stamen morphology. The encoded protein localizes to the nucleus and is linked to the regulation of secondary cell wall biogenesis, flavonoid biosynthesis, and induced systemic resistance.
