GS1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0637400 (HvGS1) on barley chromosome 7H encodes a protein with riboflavin kinase activity, FMN adenylyltransferase activity, and sn-glycerol 3-phosphatase activity, and belongs to the HAD-like superfamily. The gene is associated with nitrogen utilization, response to nitrate, glycerol anabolism, amino acid anabolism, leaf senescence, seed development, and root development. It is linked to salt stress response and localizes to the cytosol, mitochondria, and plasmalemma. Associations with grain yield, grain filling period, and protein content have been reported. Studies of related genes in other species connect the family to grain weight, grain number, spikelet number, tiller number, plant height, flag leaf senescence, nitrogen recycling, and tolerance to osmotic, salt, and oxidative stresses.
