VI1 — Oryza sativa Indica Group

Summary

BGIOSGA030372 (VI1) of Indica rice encodes a protein with Glyco_hydro_32_N, Glyco_hydro_32, Glyco_hydro_32_C, Fructan_Metab_Enzymes, Glyco_hydro_beta-prop_sf, and ConA-like_dom_sf domains, and has fructan beta-(2,6)-fructosidase, fructan exohydrolase, levanase, inulase, fructan beta-(2,1)-fructosidase, sucrose alpha-glucosidase, beta-fructofuranosidase, and O-glucosyl hydrolase activities. The gene is associated with cell wall, anther, pollen development, and sterility phenotypes, as well as domestication, seed size, grain quality, thousand grain weight, and reproductive development. It is 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, and abscisic acid response. The product localizes to the pollen tube, stress granule, vacuole, apoplast, and plant-type cell wall. Associations also include rachis length, panicle number, photosynthetic rate, grain size, grain filling, yield, chalkiness, and spikelet number. Studies of related genes in other species link the family to root pulling force
