VI1 — Oryza sativa Indica Group

Summary

BGIOSGA030373 (VI1, OiVI1) in Indica rice chromosome 9 encodes a beta-fructofuranosidase with fructan beta-(2,6)-fructosidase and beta-(2,1)-fructosidase activities (EC 3.2.1.26). The protein belongs to the Glyco_hydro_32 family and is localized to the apoplast. This gene is associated with carbohydrate metabolism, detoxification, and the biological process GO:0009856. It is associated with grain length, grain size, rachis length, panicle number, and salt tolerance (SALTTL). Studies of related genes in other species link the family to additional fructan hydrolase activities (EC 3.2.1.154 and 3.2.1.153), though these specific functions are not yet established for this rice gene.
