STR1 — Oryza sativa Indica Group

Summary

BGIOSGA023288 (symbol STR1, also known as TGW6 or OiTGW6) on chromosome 6 of Indica rice encodes a strictosidine synthase family protein with hydrolase activity, containing a strictosidine synthase conserved region and a 6-blade beta-propeller TolB-like domain. The gene is associated with grain yield, grain size, grain length, grain width, grain thickness, grain shape, and grain weight, as well as with photosynthetic ability and breeding. It is associated with carbohydrate storage, starch anabolism, alkaloid metabolism, and nitric oxide storage, and localizes to the endomembrane system and vacuole. Studies of related genes in other species connect the family to grain weight, auxin and IAA responses, and pollen development.
