GS1 — Oryza sativa Japonica

Summary

OsGS1 (OS10G0464400) encodes a protein with riboflavin kinase activity (EC 2.7.1.26), FMN adenylyltransferase activity, and sn-glycerol 3-phosphatase activity, and belongs to the riboflavin kinase and haloacid dehalogenase-like hydrolase families. In rice, this gene is associated with nitrogen utilization, photorespiration, the TCA cycle, and the biosynthesis of FMN, riboflavin, glycerol, glutathione, sucrose, phenylpropanoids, and lignin. It is linked to endosperm development, syngamy, and detoxification, and localizes to mitochondria, the cytosol, and the plasma membrane. Agronomically, OsGS1 is associated with grain yield per plant, grain weight, grain number, spikelet weight and number, panicle number, tiller number, plant height, root length, lateral root length, amylose and sucrose content, chlorophyll content, nitrogen content, grain filling period, and drought tolerance. Related genes in other species are linked to osmotic, salt, and oxidative stress tolerance.
