BG1 — Oryza sativa Japonica

Summary

OsBG1 (Os03g0600600) in rice encodes a glycoside hydrolase with lichenase and glucan endo-1,3-beta-D-glucosidase activities, placing it in the Glyco_hydro_17 family. The gene is associated with diverse biological processes including downregulation of photosynthesis, cytokinin transport, 1,3-beta-glucan breakdown, MAPK cascade, stomatal movement, and lateral root development. It localizes to the vacuole, cytoplasm, and extracellular space. OsBG1 is linked to numerous agronomically important traits such as grain yield, grain weight, grain length, grain shape, seed size, amylose content, plant height, panicle length, leaf length, brittle culm, and transpiration rate. Related genes in other species encode beta-1,3-endoglucanases.
