PIP — Daucus carota subsp. sativus

Summary

DCAR_029840, designated DcPIP (also known as DcPAP1), encodes a proline iminopeptidase belonging to the peptidase S33 and AB hydrolase families, with aminopeptidase activity. In carrots, this gene is associated with phosphatidylinositol (PtdIns) metabolism, phospholipid metabolism, and PIP biosynthesis, as well as responses to metal, salt, and thirst. The encoded protein localizes to secretory vesicles, mitochondria, and the cytosol. DcPIP is also linked to photosynthetic rate. Studies of related genes in other species connect the family to traits including phosphorus and potassium concentration, carbohydrate content, leaf water potential, relative water content, turgor pressure, net photosynthetic rate, transpiration rate, stomatal resistance, anthocyanin and chlorophyll content, root length, plant height, drought tolerance, root morphology, and salt tolerance, as well as root hydraulic conductance and water transport.
