CET2 — Brassica juncea

Summary

BJUA03G56320S (CET2, BjTFL1) on chromosome A03 of Indian mustard (Brassica juncea) encodes a phosphatidylethanolamine-binding protein (PEBP family) with DNA binding transcription factor activity and transcriptional co-regulator function. This gene is associated with photoperiodism, vernalization response, and regulation of the transition from vegetative to reproductive phase, including both upregulation and downregulation of flower development. It is linked to meristem determinacy, response to short-day conditions, and response to sucrose. Associations include flowering time traits, inflorescence development and architecture, seed yield, seed dormancy, shoot growth pattern, and abiotic stress response. The product localizes to the nucleus, cytoplasm, vacuole, ER, vesicle, and plasmalemma. Studies of related genes in other species link the family to inflorescence meristem maintenance, plant architecture, and non-photochemical quenching.
