FT — Solanum tuberosum

Summary

PGSC0003DMG400023365 (FT, also known as StSP6A, StTSF, StHD3A) on potato chromosome 5 encodes a phosphatidylethanolamine-binding protein (PEBP family) with multiple annotated molecular functions including DNA binding, transcription factor activity, and peptide-O-fucosyltransferase activity. The gene is associated with tuberization, particularly under high temperature, as well as flower bud development. It is linked to response to short-day conditions and regulation of signal transduction. Associations extend to yield, heat tolerance, tuber morphology, and starch grain synthesis. The gene product localizes to plasmodesmata, endoplasmic reticulum, plastids, and other cellular compartments. Studies of related genes in other species connect the PEBP family to flowering time, plant architecture, photoperiod response, and inflorescence development.
