HAG1 — Brassica juncea

Summary

BJUB02G64480S (BjHAG1, also known as BjMYB28) on chromosome B02 of Indian mustard encodes a DNA-binding transcription factor with sequence-specific DNA binding, transcription cis-regulatory region binding, and additional molecular functions including calcium ion binding, kinase binding, and protein binding. It is localized to the nucleus. The gene is associated with regulation of glucosinolate biosynthetic process, cellular response to sulfur starvation, induced systemic resistance, regulation of defense response to insect, and response to bacteria. Associations with agronomically relevant traits include seed protein content, flowering time trait, shoot elongation under submergence, phosphorus response, aphid response trait, insect damage response trait, disease tolerance, root mass density, lateral root length, and stomatal opening. Related genes in other species link the family to glucosinolate content, drought tolerance, and resistance to herbivory and fungal pathogens.
