CET2 — Brassica juncea

Summary

BJUB08G60370S (CET2, BjTFL1) on chromosome B08 of Indian mustard encodes a phosphatidylethanolamine-binding protein (PEBP family) with transcriptional co-regulator and DNA-binding transcription factor activity. The gene is associated with photoperiodism, vernalization response, regulation of flowering time, and meristem determinacy, as well as responses to short days and sucrose. It has been linked to traits including flowering time, inflorescence development, spikelet floret size, seed yield, seed dormancy, senescence, and abiotic stress response. The product localises 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 determinate inflorescence formation, as well as plant height and spikelet size.
