VP1 — Brassica juncea

Summary

BJUB08G46780S (VP1, BjHSI2) on chromosome B08 of Indian mustard (Brassica juncea) encodes a B3 DNA-binding domain transcription factor with zinc-finger motifs (Zfn_VAL1-3_N, Znf_CW) that binds DNA, transcription cis-regulatory regions, proteins and zinc. It is associated with regulation of seed maturation, seed development, upregulation of seed germination, ABA signaling, response to sucrose, photoperiodism, flowering, flower development, downregulation of transcription, and regulation of DNA-templated transcription. The gene is linked to seed size, width, length and weight, germination rate, flowering time and root morphology. It has been connected to somatic embryonic phenotypes, seed maturation to vegetative growth transition, vernalization response, FLC repression, drought stress tolerance, sugar response, lipid biosynthesis, photomorphogenesis and seed dormancy. The protein localises to the nucleus, cytoplasm, mitochondria and Sin3-type complex. Related genes in other species link the family to seed maturation gene expression and flowering time.
