FG — Solanum tuberosum

Summary

StFG (PGSC0003DMG400026690) on potato chromosome 1 encodes a CONSTANS-like protein containing a CCT domain and is annotated with numerous molecular functions including OGTase, peptide-O-fucosyltransferase, and histone methylase activities. The gene is associated with regulation of the phytochrome signaling pathway, photoperiodic flowering, chlorophyll breakdown, and zeatin anabolism. It has been linked to traits including photoperiod sensitivity, subterranean shoot axis tuber size, vegetative vigor, leaf margin morphology, iron content, and responses to water stress, nitrogen, and glyphosate. Associations with flower and fruit development, abscisic acid response, and Botrytis cinerea resistance are also noted. Studies of related genes in other species connect the family to photoperiod-dependent flowering, tuberization, stress tolerance, and root architecture.
