FG — Solanum tuberosum

Summary

StFG (PGSC0003DMG402010056) on potato chromosome 2 encodes a CONSTANS-like protein with B-box and CCT domains, and is annotated with diverse molecular functions including OGTase, peptide-O-fucosyltransferase, histone methylase, and red/far-red light photoreceptor activities. The gene is associated with regulation of the phytochrome signaling pathway, photoperiodic flowering, zeatin biosynthesis, chlorophyll breakdown, and responses to short-day and long-day conditions. It has been linked to traits including photoperiod sensitivity, tuber size, vegetative vigor, leaf angle, iron content, and responses to water stress, nitrogen, and glyphosate. Associations also include flower and fruit development, seed protein content, and resistance to spot blotch and nematodes. Related genes in other species are associated with photoperiod-dependent flowering, tuberization, stress tolerance, and root architecture.
