BG1 — Oryza sativa Japonica

Summary

OsBG1 (OS01G0941200) encodes a glycoside hydrolase family 17 protein with lichenase and glucan endo-1,3-beta-D-glucosidase activity. This rice gene on chromosome 1 is associated with multiple biological processes including 1,3-beta-glucan breakdown, regulation of photosynthesis, cytokinin transport, MAPK cascade, stomatal movement, lateral root development, and chlorophyll fluorescence. The encoded protein localizes to the vacuole, cytoplasm, and extracellular space. OsBG1 is linked to numerous agronomically important traits including grain yield, grain weight, grain size, grain length, grain number, plant height, panicle length, leaf length, seed size, amylose content, sucrose content, protein content, brittle culm, embryoless seed, transpiration rate, and stomatal resistance. Related genes in other species encode beta-1,3-endoglucanase proteins.
