FG — Solanum tuberosum

Summary

StFG (PGSC0003DMG400006387) on potato chromosome 4 encodes a CONSTANS-like protein with a CCT domain and has been annotated with numerous molecular functions including OGTase, peptide-O-fucosyltransferase, glutamate-tRNA ligase, histone methylase, and red/far-red light photoreceptor activities. The gene is associated with regulation of the phytochrome signaling pathway, zeatin and trans-zeatin anabolism, upregulation of chlorophyll breakdown and short-day photoperiodic flowering, flower formation, response to long-day and short-day conditions, and negative regulation of cellulose anabolism. It has been linked to traits including subterranean shoot axis tuber size, photoperiod sensitivity, water stress response, vegetative vigor, iron content, leaf angle, and sensitivities to red, far-red, UV light, nitrogen, nitrate, and glyphosate. Related genes in other species link the family to longer hypocotyls, early flowering, reduced lateral roots, and stress response.
