TFL1 — Pisum sativum

Summary

PSAT3G033760 (TFL1, TFL1a) on garden pea chromosome 3LG5 encodes a phosphatidylethanolamine-binding protein (PEBP family). The gene is associated with regulation of timing of transition from vegetative to reproductive phase, photoperiodism and flowering, regulation of photoperiodism and flowering, response to short-day and flowering, regulation of flower development, downregulation of flower development, inflorescence development, flower development, upregulation of vernalization response, vernalization response, seed germination, and cell differentiation. TFL1a localizes to the cytoplasm, nucleus, and endoplasmic reticulum. It is associated with flowering under drought stress and severe drought. Studies of related genes in other species link the family to traits including plant height, seed weight, seed dormancy, chlorophyll content, water use efficiency, stem elongation, leaf size, and days to maturity.
