PIP1 — Brachypodium distachyon

Summary

BdPIP1 (BRADI_3G56020V3) on Brachypodium distachyon chromosome 3 encodes an aquaporin family protein with channel activity, phospholipase D activity, peptide receptor activity, and protein kinase activity. It is associated with carbon dioxide transport, hydrogen peroxide membrane transport, phosphatidic acid metabolism, circadian regulation of gene expression, and response to aluminum and low humidity. The gene is linked to traits including photosynthetic rate, stomatal opening, root hair length, lateral root length, germination rate, flowering time, vegetative growth time, and responses to drought, cold, bacterial disease, powdery mildew, cadmium, and phosphorus. It localizes to the plasma membrane, cell wall, vacuole, chloroplast envelope, and plant-type cell wall. Studies of related genes in other species connect the family to water transport, drought tolerance, and grain moisture content.
