PIP1 — Brachypodium distachyon

Summary

BdPIP1 (BRADI_1G28760V3) on chromosome 1 of Brachypodium distachyon encodes a protein with aquaporin-like and MIP domains, and is annotated with phospholipase D activity, peptide binding and receptor activity, and multiple kinase-related functions. The gene is associated with carbon dioxide transport, hydrogen peroxide membrane transport, phosphatidic acid metabolism, and responses to desiccation, low humidity, and aluminum. It has been linked to traits including stomatal opening and closure, photosynthetic rate, root hair and lateral root length, germination rate, flowering time, and responses to drought, cold, bacterial disease, and powdery mildew. Additional associations include sodium uptake, cadmium concentration, brassinosteroid and ethylene sensitivity, and vegetative growth time. Studies of related genes in other species connect the family to water transport, drought tolerance, and grain moisture content.
