TFL1 — Brassica napus

Summary

BnTFL1 (TFL1) on chromosome A03 of oilseed rape (Brassica napus) encodes a phosphatidylethanolamine-binding protein (PEBP family) with DNA-binding transcription factor activity and transcriptional co-regulator function. The gene is associated with photoperiodism, the regulation of flowering time, and the transition from vegetative to reproductive phase, as well as meristem determinacy and responses to short days, vernalization, and sucrose. It is linked to traits including flowering time, inflorescence development, seed yield, heterosis, and abiotic stress response. Phenotypic associations include floral transition, inflorescence meristem identity, shoot growth pattern, seed dormancy, and senescence. The protein localizes to the nucleus, cytoplasm, vacuole, endoplasmic reticulum, vesicle, and plasmalemma. Studies of related genes in other species connect the family to inflorescence meristem maintenance and plant architecture.
