PIP1 — Brachypodium distachyon

Summary

BdPIP1 (BRADI_4G36610V3) on chromosome 4 of Brachypodium distachyon encodes a protein with aquaporin and MIP domains, and is annotated with channel activity, phospholipase D activity, peptide receptor activity, and multiple additional molecular functions including kinase activity and ubiquitin ligase binding. The gene is associated with carbon dioxide transport, hydrogen peroxide membrane transport, phosphatidic acid metabolism, circadian regulation of gene expression, and responses to desiccation, low humidity, aluminum, and bacteria. It is linked to traits including drought stress response, cold stress response, photosynthetic rate, stomatal opening and closure, root and seed growth and development, flowering time, germination rate, and disease responses to powdery mildew, downy mildew, and Fusarium graminearum. Related genes in other species connect the family to water transport, arsenic tolerance, boron tolerance, and yield-related traits such as grain moisture content and leaf water potential.
