MYB1 — Brassica juncea

Summary

BJUB03G38350S (MYB1, also known as BjPAP1) encodes a Myb-domain transcription factor with DNA-binding, transcription factor, protein dimerization, ubiquitin ligase, and protein kinase activities. It is associated with the regulation of flavonoid, proanthocyanidin, and anthocyanin biosynthesis, as well as pigmentation, seed growth, mucilage production, trichome spacing, and epidermal cell fate specification. The gene is linked to traits including flower and seed coat color, leaf color and trichome density, root epidermal cell length, light sensitivity, flavonoid content, seed longevity, cadmium and iron concentration, phosphorus uptake, lignin biosynthesis, and viral disease response. It localizes to the nucleus, root hairs, and ubiquitin ligase complexes. Related genes in other species are linked to anthocyanin pigmentation, iron accumulation, insect resistance, and salt stress tolerance.
