PS2 — Phaseolus vulgaris

Summary

PHAVU_010G140800, designated PvPS2 on chromosome 10 of French bean, encodes a protein with phosphocholine phosphatase, phosphoethanolamine phosphatase, pyrophosphatase and inorganic diphosphatase activities, belonging to the HAD-like superfamily. The gene is associated with protein tetramerization, protein dephosphorylation, cellular responses to phosphate starvation and hypoxia, and signal transduction. Its product localizes to the endoplasmic reticulum and nucleus. PvPS2 is associated with phosphate homeostasis and shows no change in response to multiple stressors. Studies of related genes in other species link the family to phosphate content, lateral root length, seed maturation and dormancy, stomatal opening, and photochemical quenching.
