AM25 — Brachypodium distachyon

Summary

BdAM25 (BRADI_1G38160V3) on chromosome 1 of Brachypodium distachyon encodes an aquaporin-like protein belonging to the MIP family, with transmembrane transporter activity for lactate, arsenite, glycerol, borate, urea and water, as well as channel activity and protein binding. The gene is associated with membrane transport of hydrogen peroxide, borate, arsenite and urea, and with responses to boron, arsenic, glucose, hypoxia and defense regulation. It has been linked to seed development, nodulation, and seed weight. Associations with boron uptake and deficiency tolerance, arsenite tolerance and uptake, aluminum tolerance and translocation, urea uptake, and pollen development and pollination have been reported. Studies of related genes in other species connect the family to boron content, arsenic accumulation, salt and drought sensitivity, water use efficiency, grain number, tiller number, biomass yield, and reproductive development.
