APS1 — Brassica juncea

Summary

BJUB01G17070S (BjAPS1) on Indian mustard chromosome B01 encodes a sulphate adenylyltransferase, with ATP:sulfate adenylyltransferase and ADGase activities. The gene is associated with sulfur and selenium metabolism, glutathione and glycogen anabolism, and response to cadmium. It is linked to starch content, starch grain synthesis, starch biosynthesis, degradation, accumulation, cycling, and metabolism, as well as photosynthetic capacity, reduced leaf starch content, and carbohydrate metabolism. Associations also include plant stress response traits, high and low temperature stress responses, short stature, anthocyanin accumulation, and reduced apical dominance. The encoded protein localises to the chloroplast envelope and stroma. Studies of related genes in other species link the family to sulfate assimilation, sulfate concentration, and flowering time.
