BG1 — Oryza sativa Japonica

Summary

OsBG1 (OS01G0941500) on rice chromosome 1 encodes a glycoside hydrolase family 17 protein with lichenase and glucan endo-1,3-beta-D-glucosidase activities. The gene is associated with diverse biological processes including downregulation of photosynthesis, regulation of photosynthesis, cytokinin transport, biofilm formation, polyketide anabolism, 1,3-beta-glucan breakdown, digestion, cellulose anabolism, regeneration, MAPK cascade, translation initiation, syngamy, chlorophyll fluorescence, lateral root development, and stomatal movement. It is linked to vacuolar, extracellular, and cytoplasmic localisation. OsBG1 is associated with multiple agronomically important traits including grain shape, grain length, grain number, grain size, grain weight, grain yield, amylose content, sucrose content, protein content, seed size, embryoless seed, brittle culm, leaf length, panicle length, plant height, transpiration rate, and stomatal resistance. Related beta-1,3-endoglucanase family members in other species are linked to glucan metabolism.
