GS1 — Oryza sativa Japonica

Summary

Rice gene GS1 (OS08G0243600) encodes a protein with riboflavin kinase activity (EC 3.1.3.21), FMN adenylyltransferase activity, and sn-glycerol 3-phosphatase activity, belonging to the Gpp1/Gpp2-like and HAD-superfamily hydrolase domains. The gene is associated with glycerol, glutathione, sucrose, and phenylpropanoid anabolism, photorespiration, the TCA cycle, nitrogen utilization, detoxification, and endosperm development. It localizes to mitochondria, cytosol, and plasmalemma. GS1 is linked to grain yield, grain weight, spikelet weight and number, panicle number, tiller number, plant height, amylose content, nitrogen content, chlorophyll content, root length, and drought tolerance. Related genes in other species are associated with salt, osmotic, and oxidative stress tolerance, as well as grain protein content and seed viability.
