GS1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0056810 (HvGS1) on barley chromosome 1H encodes a protein with riboflavin kinase activity, FMN adenylyltransferase activity, and sn-glycerol 3-phosphatase activity, and belongs to the HAD-superfamily hydrolase and beta-PGM-like domain families. The gene is associated with nitrogen utilization, response to salt and nitrate, leaf senescence, seed and root development, and glycerol anabolism. It is linked to grain yield, grain filling period, and protein content. The encoded protein localizes to the cytosol, mitochondria, and plasmalemma. Studies of related genes in other species link the family to salt, osmotic, oxidative, and formaldehyde stress tolerance, as well as desiccation tolerance. Sequence similarity connects the family to grain weight, grain number, spikelet number, tiller number, plant height, nitrogen content, and amylose content.
