PIP1 — Oryza sativa Japonica

Summary

OsPIP1 (OS07G0448100) on rice chromosome 7 encodes a plasma membrane intrinsic protein (PIP) of the aquaporin family, annotated with multiple molecular functions including phospholipase D activity, peptide binding, kinase activity, and ubiquitin ligase binding. The gene is associated with water use, seed, root, and shoot phenotypes, and with processes such as carbon dioxide transport, sucrose transport, hydrogen peroxide membrane transport, pore formation, and response to water. It has been linked to traits including drought sensitivity, water use efficiency, grain moisture content, sodium uptake, nitrogen content, cadmium concentration, root volume, lateral root length, days to heading, and bacterial and downy mildew disease responses. Related genes in other species are associated with root hydraulic conductivity, stomatal closure, mesophyll conductance, and pathogen resistance.
