PIP1 — Brachypodium distachyon

Summary

BRADI_3G18460V3 (BdPIP1) encodes a protein belonging to the aquaporin family, with multiple molecular functions including phospholipase D activity, peptide binding and receptor activity, and kinase activity. The gene is associated with carbon dioxide transport, hydrogen peroxide membrane transport, phosphatidic acid metabolism, and circadian regulation of gene expression. BdPIP1 is linked to numerous traits including drought stress tolerance, cold stress response, photosynthetic rate, stomatal opening and closure, root morphology traits (root hair length, lateral root length, root thickness), germination rate, flowering time, seed development, and disease responses to bacterial pathogens, powdery mildew, and Fusarium graminearum. The gene is also associated with responses to aluminum, desiccation, low humidity, and various nutrient responses including phosphorus and sodium uptake. Studies of related genes in other species link the family to water transport, root water uptake, and stress tolerance.
