GS1 — Phaseolus vulgaris

Summary

PvGS1 (PHAVU_003G145700) on French bean chromosome 3 encodes a protein with sn-glycerol 3-phosphatase and sugar-phosphatase activity, belonging to the Gpp1/Gpp2-like and HAD-superfamily hydrolase families. The gene is associated with glycerol anabolism, photorespiration, and nitrogen recycling and assimilation. Its product localises to both mitochondria and cytosol. Studies of related genes in other species link the family to formaldehyde stress resistance, mercury tolerance, desiccation tolerance, oxidative stress tolerance, osmotic stress tolerance, and salt tolerance. Sequence similarity connections further associate the family with amino acid content, seed viability, seed size, and oxidative stress response.
