STR1 — Oryza sativa Indica Group

Summary

BGIOSGA023287 (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 TolB-like 6-blade beta-propeller families. The gene is associated with carbohydrate storage, starch anabolism, indole alkaloid metabolism, alkaloid anabolism, alkaloid metabolism, and nitric oxide storage, and its product localises to the endomembrane system and vacuole. In this species, TGW6 is linked to yield and breeding traits, as well as grain size, thickness, width, length, shape, and weight. It has also been linked to photosynthetic ability. Studies of related genes in other species link the family to grain weight, auxin, IAA, pollen development, and general development.
