GI — Solanum tuberosum

Summary

StGI (PGSC0003DMG400001110) on potato chromosome 3 encodes a GIGANTEA protein, characterised by the GIGANTEA_C and GIGANTEA domains and localised to the nucleus. The gene is associated with the regulation of circadian rhythm, rhythmic processes, and long-day photoperiodism. It is also linked to flower development, cell differentiation, and responses to stress. In terms of metabolism, StGI is associated with starch anabolism, carbohydrate metabolism, and the regulation of flavonoid and anthocyanin anabolism. Associations with anthocyanin content and salt tolerance (related to hydrogen peroxide) have been noted. Related genes in other species are linked to plant height and salt tolerance traits.
