ADG1 — Brassica oleracea var. botrytis

Summary

BoADG1 (BOLND125_C07P040930.1_BOLND125_V1) on cauliflower chromosome 7 encodes an ADP-glucose pyrophosphorylase (ADGase). The gene is associated with starch metabolism and anabolism, as well as glycogen and ergosterol anabolism. It is linked to numerous traits including starch grain synthesis, photosynthetic ability, biomass yield, yield, water use efficiency, transpiration rate, leaf angle, and photoperiod-sensitive flowering time. The product localises to the amyloplast, chloroplast stroma, and plastid, and is part of the heterotetrameric ADPG pyrophosphorylase complex. Associations also extend to red and far-red light photoreceptor activity, light signaling pathways, circadian clock entrainment, abscisic acid metabolism, hydrogen peroxide-mediated signaling, and stomatal complex development. Studies of related genes in other species link the family to starch accumulation, flowering time, and yield traits.
