ADG2 — Cicer arietinum

Summary

CaADG2 (LOC101504730) on chickpea chromosome 7 encodes a protein with ADP-Glc_PPase, LbH_GLGC, and NTP_transferase_dom domains. The enzyme has ATP:sulfate adenylyltransferase and ADGase activities and binds ATP. It is associated with starch anabolism, glycogen anabolism, seed development, pollen germination and tube growth, response to cadmium and thirst, selenium metabolism, fatty acid anabolism, and signal transduction. The protein localizes to the amyloplast, chloroplast envelope and stroma, and the glucose-1-phosphate adenylyltransferase complex. CaADG2 is linked to starch content, starch grain synthesis, photosynthetic ability, flowering time, and drought tolerance. Related genes in other species are associated with sulfate assimilation, starch cycling, and photosynthetic capacity.
