VI1 — Oryza sativa Indica Group
Summary
BGIOSGA014155 (VI1) on chromosome 4 of Indica rice encodes a beta-fructofuranosidase (invertase) with fructan exohydrolase, levanase, inulase, and sucrose alpha-glucosidase activities, belonging to the Glyco_hydro_32 family. The gene is associated with cell wall, anther, pollen development, sterility, seed size, grain quality, thousand grain weight, and domestication traits in rice. It has been linked to nectar secretion, cellular response to gibberellin, primary root development, starch metabolism, detoxification, response to bacteria, carbohydrate metabolism, ovule development, wounding, salinity, fungal defence, thirst, and abscisic acid response. The product localizes to the pollen tube, vacuole, apoplast, plant-type cell wall, and membrane. Studies of related genes in other species link the family to male sterility, pollen germination, cell wall modification, and pathogen response.
