PIP1 — Brachypodium distachyon

Summary

BRADI_5G15970V3 (PIP1) on chromosome 5 of Brachypodium distachyon encodes an aquaporin-like protein, a member of the major intrinsic protein (MIP) family. The gene product is annotated with phospholipase D activity, peptide binding and receptor activity, kinase activity, and heme binding, and is associated with carbon dioxide transport, hydrogen peroxide membrane transport, phosphatidic acid metabolism, and circadian regulation of gene expression. It localises to the plasma membrane, plant-type cell wall, vacuole, and chloroplast envelope. PIP1 is associated with drought stress response, cold stress response, photosynthetic rate, stomatal opening and resistance, root hair and lateral root length, germination rate, flowering time, and disease tolerance to powdery mildew and bacterial pathogens. Studies of related genes in other species connect the family to water transport, root water uptake, stomatal closure, and drought tolerance.
