AP2 — Brassica juncea

Summary

BjAP2 (BJUA03G03900S) on chromosome A03 of Indian mustard encodes a DNA-binding transcription factor with an AP2/ERF domain that acts as a transcription corepressor. It is associated with the regulation of seed development, starch biosynthesis, endosperm development, floral organ identity and abscission, meristem maintenance, and the transition from vegetative to reproductive phase. The gene is linked to heat generation, fatty acid oxidation, lipogenesis, gibberellic acid homeostasis, and vascular tissue pattern formation. Associations with agronomic traits include seed weight, harvest index, germination rate, drought tolerance, heterosis, and cytoplasmic male sterility. It is also linked to floral development, inflorescence architecture, seed yield, seed mass, and photoassimilate translocation. The protein localises to the nucleus, cytoplasm, and transcription regulator complex.
