VI1 — Oryza sativa Indica Group
Summary
BGIOSGA016364 (VI1, also known as CIN2) encodes a beta-fructofuranosidase (invertase) with fructan exohydrolase, inulase, and sucrose alpha-glucosidase activities, belonging to the glycosyl hydrolase 32 family. The gene is associated with cell wall, anther, pollen, and seed development, as well as domestication, grain quality, thousand grain weight, and organ size in rice. It has been linked to carbohydrate and starch metabolism, nectar secretion, response to gibberellin, abscisic acid, wounding, bacteria, fungi, and salinity. The protein localizes to the apoplast, vacuole, plant-type cell wall, pollen tube, and membrane. Studies of related genes in other species link the family to pathogen response, sucrose uptake, and male sterility, as well as grain yield, kernel number, seed size, and stay-green traits.
