VI1 — Oryza sativa Indica Group

Summary

BGIOSGA016363 (VI1, also known as CIN3) encodes a beta-fructofuranosidase with fructan exohydrolase, inulase, and sucrose alpha-glucosidase activities, belonging to the Glyco_hydro_32 family. In indica rice, this gene is associated with cell wall structure, sterility, anther and pollen development, seed size, grain quality, thousand grain weight, domestication, and reproductive development. It is linked to carbohydrate and starch metabolism, nectar secretion, responses to gibberellin, abscisic acid, wounding, bacteria, fungi, and salinity, as well as primary root and ovule development. The protein localizes to the apoplast, vacuole, cell wall, pollen tube, and membrane. Associations also include panicle number, grain size, photosynthetic rate, rachis length, reproductive period, and salt tolerance. Studies of related genes in other species link the family to male sterility, pollen germination, pathogen response, and cell wall modification.
