TIP1 — Brachypodium distachyon

Summary

BdTIP1 (BRADI_1G75290V3) on chromosome 1 of Brachypodium distachyon encodes a protein with an aquaporin-like domain and MIP family signature, annotated with urea transmembrane transporter activity, channel activity, water channel activity, heme binding, and mRNA binding. It is associated with vacuole organization, leaf development, polar cell growth, membrane transport, carbohydrate metabolism, and responses to abscisic acid, salt, and osmotic stress. The gene is linked to seed growth and development, oleic acid content, plant stress response, salt tolerance, senescence, lateral root emergence, root water transport, seed oil content, thermotolerance, and lipid metabolism. It localizes to the tonoplast, vacuole, Golgi stack, and chloroplast envelope. Studies of related genes in other species connect the family to water and urea transport, salt and drought tolerance, grain size, plant height, and stomatal regulation.
