VP1 — Brassica juncea

Summary

BJUA05G12460S (VP1, BjHSI2) encodes a B3 DNA-binding domain transcription factor with zinc-finger domains (Zfn_VAL1-3_N, Znf_CW) that localises to the nucleus and cytoplasm. It is associated with regulation of seed maturation, seed development, and the transition from seed maturation to vegetative growth. The gene has been connected to seed size, seed width, seed length, seed weight, and germination rate, as well as flowering time, photoperiodism, flower development, and root morphology. It is linked to responses to abscisic acid and sucrose, ABA signalling, and FLC repression. Associations also include drought stress tolerance, somatic embryonic phenotypes, and altered H3K27me3 distribution. Studies of related genes in other species link the family to flowering time, delayed vegetative phase change, and seed maturation gene expression.
