AM25 — Brachypodium distachyon

Summary

BdAM25 (BRADI_3G08930V3) on chromosome 3 of Brachypodium distachyon encodes an aquaporin-like protein with transmembrane transporter activity for lactate, arsenite, silicate, glycerol, borate, urea and water, as well as channel activity and histone H3T11 kinase activity. The gene is associated with transport of lactate, silicic acid, borate, arsenite, urea and hydrogen peroxide, and with responses to boron, arsenic, glucose, hypoxia and defense regulation, as well as seed development and nodulation. The protein localises to the plasma membrane, lateral plasma membrane, peribacteroid membrane, Casparian strip, endoplasmic reticulum and cytoplasm. BdAM25 is associated with seed weight, boron uptake, boron deficiency tolerance, arsenite tolerance, aluminum tolerance, arsenic distribution, urea uptake, pollen development and pollination. Studies of related genes in other species connect the family to boron content, arsenic accumulation, salt and drought responses, grain number, biomass yield, water use efficiency and reproductive development.
