ADG1 — Solanum tuberosum

Summary

PGSC0003DMG400031084 (ADG1, also known as AGPB1, GLGS, APS1, StGLGS, StADG1, or StAPS1) on potato chromosome 7 encodes a protein with ADP-glucose pyrophosphorylase activity (EC 2.7.7.27). The gene is associated with starch anabolism, metabolism, and breakdown, as well as glycogen anabolism, sulfur metabolism, and abscisic acid metabolism. It is linked to starch yield, tuber size, biomass yield, photosynthetic ability, and yield traits. The encoded protein localizes to the amyloplast, plastid, chloroplast stroma, and the ADP-glucose pyrophosphorylase complex. The gene is also associated with responses to red and far-red light, photoperiod-sensitive flowering, circadian regulation, and stomatal development. Related genes in other species are linked to starch accumulation, flowering time, and tuber yield.
