PIP — Pisum sativum

Summary

PSAT1G212200 (PsPIP) encodes a proline iminopeptidase (EC 3.4.11.5) with aminopeptidase activity, belonging to the peptidase S33 and alpha/beta hydrolase fold families. The gene is associated with water transport, proteolysis, and responses to nitrate, salt, heat, metal, and thirst, as well as heat acclimation, nodulation, and virus-induced PTGS. It is linked to traits including water absorption by seed, calcium concentration, and photosynthetic rate. The encoded protein localises to the cytosol, cytoplasm, mitochondria, and secretory vesicles. Studies of related genes in other species connect the family to drought tolerance, leaf water potential, transpiration rate, stomatal resistance and opening, chlorophyll content, relative biomass, sodium and fructose content, root dry weight and morphology, and root hydraulic conductance.
