GS1 — Oryza sativa Japonica

Summary

OsGS1 (OS06G0109500) encodes a protein with riboflavin kinase activity, FMN adenylyltransferase activity, sugar-phosphatase activity, and sn-glycerol 3-phosphatase activity, and belongs to the HAD-superfamily hydrolase and beta-PGM-like domain families. In rice, the gene is associated with nitrogen utilization and response to nitrate, photorespiration, the TCA cycle, and the biosynthesis of glycerol, glutathione, sucrose, lignin, and phenylpropanoids. It is linked to endosperm development, syngamy, and detoxification, and localizes to the cytosol, mitochondria, and plasmalemma. OsGS1 is associated with grain yield, grain weight, grain number, spikelet weight and number, panicle number, tiller number, plant height, amylose content, sucrose content, nitrogen content, root length, lateral root length, chlorophyll content, and drought tolerance.
