GL1 — Brassica juncea

Summary

BJUA04G11030S (GL1, BjMYB23) on Indian mustard chromosome A04 encodes a Myb-domain transcription factor with DNA-binding, transcription factor activity, and protein dimerization activity. It is associated with the regulation of trichome morphogenesis, spacing, and cell fate specification, as well as plant epidermis development, defense response to insects, and positive regulation of anthocyanin biosynthesis. The gene is linked to leaf trichome density, root hair length and development, seed coat morphology, seed protein and oil content, flavonoid and anthocyanin content, and responses to phosphorus, iron, jasmonic acid, and osmotic stress. It localizes to the nucleus and root hair. Related genes in other species are linked to epidermal differentiation, root hair patterning, trichome development, and seed coat mucilage accumulation.
