PIP — Lactuca sativa

Summary

LsPIP, encoded by the gene LSAT_V11C500268360 on chromosome 5 of garden lettuce (Lactuca sativa), is a proline iminopeptidase belonging to the peptidase S33 and AB hydrolase families, with aminopeptidase activity. The gene is associated with responses to metal, salt, and thirst, and its product localizes to the secretory vesicle, mitochondria, cytosol, and cytoplasm. LsPIP has been linked to phosphorus and potassium concentrations, leaf relative water content, and photosynthetic rate. Studies of related genes in other species connect the family to traits including carbohydrate content, leaf water potential, turgor pressure, net photosynthetic and transpiration rates, stomatal resistance, anthocyanin and chlorophyll content, root length and morphology, plant height, drought tolerance, and salt tolerance, as well as root hydraulic conductance and water transport.
