TFL1 — Brassica napus

Summary

BnTFL1 (TFL1) on chromosome C03 of oilseed rape (Brassica napus) encodes a phosphatidylethanolamine-binding protein (PEBP family) with transcriptional co-regulator and DNA-binding transcription factor activity. The gene is associated with the regulation of flowering time, photoperiodism, and the transition from vegetative to reproductive phase, as well as meristem determinacy and inflorescence development. It has been linked to traits including flowering time, photoperiod-sensitive flowering, inflorescence architecture, seed yield, heterosis, and abiotic stress response. The encoded protein localises to the cytoplasm, nucleus, vacuole, ER, vesicle, and plasmalemma, and interacts with FD. Studies of related genes in other species connect the family to inflorescence meristem maintenance, plant architecture, and determinate inflorescence formation.
