ADG1 — Brassica juncea

Summary

BJUA06G08670S (BjADG1, also known as BjAPS1) on Indian mustard chromosome A06 encodes a protein with ADP-Glc_PPase, NTP_transferase, and nucleotide-diphosphosugar transfer domains. The enzyme possesses ADGase activity and is associated with starch and glycogen anabolism, sulfur metabolism, abscisic acid metabolism, and glutathione anabolism. It localizes to the amyloplast, chloroplast stroma, and plastid, and is part of the heterotetrameric ADPG pyrophosphorylase complex. The gene is linked to starch content and synthesis, biomass yield, yield traits, photosynthetic ability, water use efficiency, transpiration rate, leaf angle, root and shoot morphology, photoperiod-sensitive flowering time, and responses to red light, UV-B light, glyphosate, gibberellic acid, and jasmonic acid. Studies of related genes in other species link the family to starch production, flowering time, circadian rhythm, photomorphogenesis, and yield-related traits.
