GS1 — Phaseolus vulgaris

Summary

PHAVU_003G145800 (GS1, also known as PvGPP1, PvGPP2, PvPYRP3) on chromosome 3 of French bean (Phaseolus vulgaris) encodes a member of the Gpp1/Gpp2-like family with sn-glycerol 3-phosphatase and sugar-phosphatase activity. The gene is associated with glycerol anabolism, photorespiration, and nitrogen recycling and assimilation. Its product localises to mitochondria and cytosol. Related genes in other species link the family to tolerance of formaldehyde, mercury, desiccation, oxidative stress, osmotic stress, and salt stress, as well as to seed viability, seed size, and amino acid content.
