VP1 — Brassica juncea

Summary

BJUB03G32040S (symbol VP1, preferred name BjLEC2) on chromosome B03 of Indian mustard (Brassica juncea) encodes a B3 DNA-binding domain transcription factor that binds DNA and zinc and localises to the nucleus and cytoplasm. The gene is associated with positive regulation of auxin biosynthesis, seed oilbody biogenesis, photoperiodism, flowering, flower development, embryo development ending in seed dormancy, ABA signalling and response, and DNA-dependent transcription. It has been linked to seed traits including width, length, weight, size, oil content, protein content, starch content, sucrose content, and desiccation tolerance, as well as triacylglycerol accumulation, fatty acid metabolism, somatic embryogenesis, trichome formation, lateral root formation, and cell dedifferentiation. Studies of related genes in other species link the family to seed maturation, oil accumulation in leaves, and somatic embryogenesis.
