PIP1 — Brachypodium distachyon

Summary

BdPIP1 (BRADI_5G18170V3) on chromosome 5 of Brachypodium distachyon encodes an aquaporin-like protein with channel activity, phospholipase D activity, peptide receptor activity, and multiple other molecular functions including kinase and ATP hydrolase activities. It is associated with carbon dioxide transport, hydrogen peroxide membrane transport, phosphatidic acid metabolism, circadian regulation of gene expression, and responses to aluminum, low humidity, and bacteria. The gene is linked to numerous agronomically relevant traits including drought stress response, cold stress response, photosynthetic rate, stomatal resistance and opening, root hair length, lateral root length, germination rate, flowering time, seed growth and development, and disease tolerance. It localizes to the plasma membrane region, plant-type cell wall, chloroplast envelope, and other cellular compartments. Studies of related genes in other species connect the family to water transport, root water uptake, stomatal closure, and stress tolerance.
