FG — Solanum tuberosum

Summary

StFG (PGSC0003DMG400026311) on potato chromosome 8 encodes a CONSTANS-like protein containing B-box and CCT domains, and is annotated with diverse molecular functions including OGTase, peptide-O-fucosyltransferase, and histone methylase activities. The gene is associated with regulation of phytochrome signaling, flowering under short-day photoperiods, chlorophyll breakdown, zeatin biosynthesis, and responses to light quality and duration. StFG is linked to traits including tuber size, photoperiod sensitivity, vegetative vigor, leaf morphology, iron content, and stress responses such as water stress, nematode damage, and glyphosate sensitivity. Studies of related genes in other species connect the family to photoperiod-dependent flowering, tuberization, root architecture, stress tolerance, and disease resistance.
