AM25 — Brachypodium distachyon

Summary

BdAM25 (BRADI_3G17101V3) on chromosome 3 of Brachypodium distachyon encodes an aquaporin-like protein with a major intrinsic protein (MIP) domain. It is annotated with transmembrane transporter activities for lactate, arsenite, silicate, glycerol, borate, urea, and water, as well as channel activity and protein binding. The gene is associated with the transport of lactate, silicic acid, borate, arsenite, urea, and hydrogen peroxide, and with responses to boron, arsenic, glucose, hypoxia, and defense regulation. It is linked to seed development, nodulation, and seed weight. Localization evidence places the product at the lateral plasma membrane, peribacteroid membrane, Casparian strip, ER, and cytoplasm. Related genes in other species are linked to boron uptake and deficiency tolerance, arsenite and aluminum tolerance, urea uptake, pollen development, and traits such as grain number, biomass yield, and water use efficiency.
