GL1 — Brassica juncea

Summary

BJUA02G37960S (symbol GL1, preferred name BjWER) on chromosome A02 of Indian mustard (Brassica juncea) encodes a MYB-family transcription factor with DNA-binding, protein-dimerization and protein-kinase activities. The gene is associated with epidermal cell fate specification, trichome spacing, root-hair differentiation, stomatal complex formation, and positive regulation of anthocyanin biosynthesis. It is linked to brassinosteroid-signalling inhibition, autophagy, vacuole organization, root meristem size, and green leaf volatile biosynthesis. Associations with agronomic traits include leaf trichome density and morphology, root epidermal cell length and thickness, flavonoid and anthocyanin content, flowering time, seed development, and responses to drought, salt, low temperature, iron deficiency, and disease. The product localizes to the nucleus, plasma membrane, cytoplasm, vesicles, and root hairs. Related genes in other species are linked to epidermal patterning, trichome and root-hair differentiation, anthocyanin accumulation, and iron homeostasis.
