BG1 — Oryza sativa Japonica

Summary

OsBG1 (OS01G0942300) encodes a glycoside hydrolase family 17 protein with glucan exo-1,3-beta-glucosidase, cellulase, lichenase, and glucan endo-1,3-beta-D-glucosidase activities. The gene is associated with diverse biological processes including cytokinin transport, regulation of photosynthesis, chlorophyll breakdown, MAPK cascade signaling, stomatal movement, and lateral root development. It localizes to the apoplast, plant-type cell wall, secretory vesicles, vacuole, ER, Golgi, and plasmodesmata. In rice, OsBG1 is linked to cellulose and panicle phenotypes. The gene is associated with numerous agronomic traits including grain yield, grain weight, grain length, grain shape, amylose content, plant height, panicle length, seed size, protein content, sucrose content, nitrate uptake, transpiration rate, stomatal resistance, and salt tolerance. It is also linked to disease resistance, drought response, osmotic stress tolerance, and anthocyanin accumulation.
