VP1 — Brassica juncea

Summary

BJUB06G39990S (symbol VP1, preferred name BjHSI2) encodes a B3 DNA-binding domain transcription factor with zinc-finger motifs (Zfn_VAL1-3_N, Znf_CW) that localises to the nucleus, cytoplasm and mitochondria. It is associated with regulation of seed maturation, seed development, seed size, seed weight, seed length and width, germination rate, flowering time, flower development, photoperiodism, response to abscisic acid and sucrose, ABA signalling, and root morphology. The gene is linked to somatic embryonic phenotypes, altered H3K27me3 distribution, the seed-to-vegetative transition, vernalization response, FLC repression, drought stress tolerance, lipid biosynthesis, sugar response, and embryo and seedling development. Related genes in other species are linked to seed maturation gene expression, flowering transition, and delayed vegetative phase change and flowering.
