TFL1 — Brassica oleracea

Summary

BoTFL1 (BOLC102_C03P002350.1_BOLC102_V1) on cabbage chromosome 3 encodes a phosphatidylethanolamine-binding protein (PEBP family) with DNA-binding transcription factor activity and transcriptional co-regulator functions. The gene is associated with photoperiodism, vernalization response, meristem determinacy, flower development, cellular respiration, vacuolar protein sorting, and response to sucrose and short-day conditions. It localizes to the nucleus, cytoplasm, plasmalemma, ER, vacuole, and vesicles. BoTFL1 is linked to flowering time, inflorescence architecture and meristem identity, seed yield, seed dormancy, senescence, shoot growth pattern, heterosis, abscisic acid sensitivity, and abiotic stress response. Studies of related genes in other species connect the family to inflorescence meristem maintenance, plant architecture, and non-photochemical quenching, as well as plant height and spikelet size.
