STR1 — Oryza sativa Indica Group

Summary

BGIOSGA023286 (symbol STR1, also known as TGW6 or OiTGW6) on chromosome 6 of Indica rice encodes a protein with strictosidine synthase and hydrolase activities, belonging to the strictosidine synthase conserved region and 6-blade β-propeller TolB-like families. It is associated with carbohydrate storage, starch anabolism, indole alkaloid metabolism, and nitric oxide storage, and localises to the endomembrane system and vacuole. The gene is linked to yield and breeding, and has been connected to grain size, thickness, width, length, shape, and weight, as well as grain yield and photosynthetic ability. Studies of related genes in other species link the family to grain weight, auxin, IAA, pollen development, and development.
