AM25 — Brachypodium distachyon

Summary

BdAM25 (BRADI_2G32890V3) on chromosome 2 of Brachypodium distachyon encodes an aquaporin-like protein with transmembrane transporter activities 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. It is linked to seed development, nodulation, and seed weight, and to phenotypes including boron uptake and deficiency tolerance, arsenite tolerance and uptake, aluminum tolerance and translocation, urea uptake, pollen development and pollination. Localisation evidence connects the product to the lateral plasma membrane, peribacteroid membrane, Casparian strip, endoplasmic reticulum, extracellular region and cytoplasm. Related genes in other species link it to boron content, arsenic accumulation, salt and drought sensitivity, grain number, biomass yield, water use efficiency and flowering time.
