FT — Lactuca sativa

Summary

LsFT (LSAT_V11C200057260) on chromosome 2 of garden lettuce encodes a phosphatidylethanolamine-binding protein (PEBP family) with sequence-specific DNA binding and transcription factor activity. The gene is associated with photoperiodism, floral whorl development, meristem identity and determinacy, response to short days, vernalization, strigolactone response, and circadian clock temperature compensation. It has been linked to traits including photoperiod-sensitive flowering time, inflorescence development and branch arrangement, spikelet floret size, fruit set, seed viability, leaf length and position, vegetative vigor, shoot axis branching, axillary bud dormancy, and responses to temperature, UV light, and viral disease. Studies of related genes in other species connect the family to tuberization, plant architecture, photoperiod sensitivity, and yield components.
