PIP — Beta vulgaris subsp. vulgaris

Summary

BvPIP (BVRB_9G222420) on sugar beet chromosome 9 encodes a proline iminopeptidase belonging to the peptidase S33 and AB hydrolase families, with aminopeptidase activity. The gene is associated with pH reduction, response to metal, salt stress, nitric oxide storage, and thirst response. Its product localizes to secretory vesicles, mitochondria, and the cytosol. BvPIP is associated with 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. In Arabidopsis, family members have been linked to root hydraulic conductance, reduced pollen viability, delayed post-stress growth, and water transport.
