FT — Pisum sativum

Summary

PsFT (PSAT1G096760) on garden pea chromosome 1LG6 encodes a phosphatidylethanolamine-binding protein (PEBP family) with sequence-specific DNA binding and transcription factor activity. It is associated with photoperiodism, vernalization response, floral whorl development, meristem identity and determinacy, secondary shoot formation, and responses to strigolactone, nitrogen and potassium starvation. The gene is linked to photoperiod-sensitive flowering time, inflorescence and pistil morphology, fruit set, seed viability, vegetative vigor, leaf and stem length, branching, axillary bud dormancy, spot blotch response, temperature and UV light sensitivity, and starch grain synthesis. Related genes in other species link the family to flowering time, photoperiodic flowering response, floral transition, seed dormancy, seed yield, fruit ripening, and inflorescence architecture.
