VI1 — Oryza sativa Indica Group

Summary

BGIOSGA040224 (symbol VI1, also known as OiVI1) in Indica rice encodes a protein with beta-fructofuranosidase activity, including fructan beta-(2,6)-fructosidase and sucrose 1F-fructosyltransferase activities, and belongs to the GH32 enzyme family. The product is associated with carbohydrate metabolism, detoxification, and the vacuole and apoplast. This gene has been linked to grain length, grain size, rachis length, panicle number, and salt tolerance (SALTTL). Related genes in other species, such as CIN1, CIN6, CIN7, and 6-FEH, link the broader gene family to sucrose hydrolysis and fructan processing, though these specific functions are not yet established for this Indica rice gene.
