TFL1 — Brassica oleracea var. botrytis

Summary

BoTFL1 (BOLND125_C03P001820.1_BOLND125_V1) on cauliflower chromosome 3 encodes a phosphatidylethanolamine-binding protein (PEBP family) with DNA-binding transcription factor activity and transcriptional co-regulator function. The gene is associated with flower formation, meristem determinacy, and the regulation of flowering time, including photoperiodism, vernalization response, and the transition from vegetative to reproductive phase. It is linked to inflorescence architecture, meristem identity, seed yield, seed dormancy, shoot growth pattern, and senescence. Associations also include response to sucrose, vacuolar protein sorting, and abiotic stress response. The protein localizes to the nucleus, cytoplasm, ER, vacuole, vesicle, and plasmalemma. Related genes in other species link the family to inflorescence development, plant architecture, plant height, spikelet size, and seed yield traits.
