VP1 — Brassica juncea

Summary

BJUA07G10170S (symbol VP1, preferred name BjLEC2) on Indian mustard chromosome A07 encodes a B3 DNA-binding domain transcription factor of the LEC2-like family. The protein localises to the nucleus and cytoplasm, binds DNA and zinc, and is associated with transcription cis-regulatory region binding and DNA binding transcription factor activity. It is associated with positive regulation of auxin biosynthetic process, seed oilbody biogenesis, photoperiodism, flowering, flower development, embryo development ending in seed dormancy, abscisic acid signaling and response, and DNA-dependent transcription. Associations with seed traits include seed width, length, weight, and size. It is also linked to embryo development, somatic embryogenesis, trichome formation, lateral root formation, cellular dedifferentiation, and gibberellin biosynthesis. Studies of related genes in other species connect the family to seed maturation, oil accumulation in leaves, and fatty acid metabolism.
