VI1 — Oryza sativa Indica Group

Summary

BGIOSGA007345 (VI1) in Indica rice encodes a beta-fructofuranosidase with sucrose 1F-fructosyltransferase, fructan exohydrolase, levanase, inulase, 6G-fructosyltransferase, and beta-fructofuranosidase activities. The gene is associated with cell wall, anther, pollen development, and sterility phenotypes, as well as seed size, grain quality, thousand grain weight, and domestication. It is linked to nectar secretion, sucrose and starch metabolism, response to abscisic acid, gibberellin, wounding, bacteria, fungi, and salinity. Localization evidence connects the product to the vacuole, vacuolar lumen and membrane, plant-type cell wall, pollen tube, and extracellular space. Associations with grain filling, panicle number, grain size, chalkiness, endosperm development, yield, photosynthetic rate, and reproductive period have also been reported.
