FT — Solanum tuberosum

Summary

PGSC0003DMG400016179, the potato (Solanum tuberosum) FT gene on chromosome 11, encodes a phosphatidylethanolamine-binding protein (PEBP family) with multiple annotated molecular functions including DNA binding, transcription factor activity, and mRNA regulatory element binding translation repressor activity. StFT is associated with photoperiodism, flowering time regulation, and tuberization, including responses to short-day conditions and vernalization. It is linked to floral whorl development, meristem identity and determinacy, secondary shoot formation, and circadian clock temperature compensation. The gene has been connected to yield, tuber yield and tuberization under high temperature, heat tolerance, flower bud development, strigolactone signaling, axillary bud dormancy and outgrowth, branching, and stomatal opening. Additional associations include photoperiod sensitivity, fruit set, seed viability, leaf and inflorescence traits, and responses to strigolactone, hormones, and temperature stress.
