TFL1 — Phaseolus vulgaris

Summary

PvTFL1 (PHAVU_001G189200) on chromosome 1 of French bean encodes a phosphatidylethanolamine-binding protein (PEBP family). The gene is associated with the regulation of flowering time, photoperiodism, and the transition from vegetative to reproductive phase, as well as with inflorescence and flower development, cell differentiation, and responses to short-day conditions. It is linked to upregulation of vernalization response and downregulation of flower development. Associations with seed size and plant height have been noted. The protein localises to the cytoplasm, nucleus, and endoplasmic reticulum. Studies of related genes in other species link the family to traits including days to maturity, seed weight, seed dormancy, stem elongation, leaf size, chlorophyll content, and water use efficiency.
