AM25 — Brachypodium distachyon

Summary

BdAM25 (BRADI_4G03330V3) on chromosome 4 of Brachypodium distachyon encodes an aquaporin-like protein with transmembrane transporter activities for lactate, arsenite, glycerol, borate, urea and water, as well as channel activity and protein binding. The gene is associated with membrane transport processes including borate, arsenite and hydrogen peroxide transport, responses to boron, arsenic, glucose and hypoxia, regulation of defense response, nodulation and seed development. It localises to the plasma membrane, ER, cytoplasm and nucleus. BdAM25 is linked to seed weight, boron uptake and deficiency tolerance, arsenite and aluminum tolerance, urea uptake, pollen development and pollination. Studies of related genes in other species connect the family to arsenic accumulation, silicon transport, salt and drought responses, grain number, biomass yield and water use efficiency.
