BG1 — Oryza sativa Japonica

Summary

OsBG1 (OS06G0531000) encodes a glycoside hydrolase family 17 protein with glucan endo-1,3-beta-D-glucosidase activity (EC 3.2.1.39) and lichenase activity, and is associated with protein homodimerization. The gene is linked to diverse biological processes including cytokinin transport, regulation of photosynthesis, MAPK cascade, stomatal movement, lateral root development, and 1,3-beta-glucan breakdown. It localizes to the vacuole, extracellular space, and plasma membrane. OsBG1 has been connected to numerous agronomically important traits such as grain yield, grain weight, grain size, grain length, grain number, amylose content, protein content, plant height, panicle length, leaf length, seed size, brittle culm, embryoless seed, sucrose content, transpiration rate, and stomatal resistance. Studies of related genes in other species link the family to additional glucanase activities.
