FT — Pisum sativum

Summary

PSAT3G090720 (FTa1, also known as FT) on garden pea chromosome 3LG5 encodes a phosphatidylethanolamine-binding protein (PEBP) family member with DNA-binding transcription factor activity and mRNA regulatory element binding translation repressor activity. This gene is associated with photoperiodism, floral whorl development, maintenance of floral meristem identity, meristem determinacy, and regulation of secondary shoot formation. It has been linked to photoperiod-sensitive flowering time, inflorescence development and morphology, axillary bud dormancy and outgrowth, shoot axis branching, plant male sterility, seed viability, fruit set, leaf length, stem length, vegetative vigor, temperature stress response, viral disease response, and starch grain synthesis. The gene product localizes to the plasmodesma, endoplasmic reticulum, Golgi complex, plastid, mitochondria, and cytosol. Related genes in other species are linked to photoperiodic flowering response, floral transition, seed dormancy, and inflorescence architecture.
