VP1 — Brassica juncea

Summary

BJUA03G43550S (symbol VP1, also known as BjHSI2, BjVAL1) on chromosome A03 of Indian mustard (Brassica juncea) encodes a B3 DNA-binding domain transcription factor with zinc-binding activity. The product is associated with the regulation of seed maturation, seed development, and the transition from seed maturation to vegetative growth. It is linked to abscisic acid signaling, response to sucrose, photoperiodism, and flower development. Associations with seed size, seed width, seed length, seed weight, germination rate, flowering time, and root morphology have been observed. The gene is also connected to drought stress tolerance, vernalization response, FLC repression, lipid biosynthesis, and sugar response. Localization evidence places the product in the nucleus, cytoplasm, mitochondria, and the Sin3-type complex. Studies of related genes in other species link the family to flowering time and seed maturation gene expression.
