AM25 — Brachypodium distachyon

Summary

BdAM25 (BRADI_1G45200V3) on chromosome 1 of Brachypodium distachyon encodes an aquaporin-like protein with multiple transmembrane transporter activities, including water, glycerol, urea, borate, silicate, arsenite and lactate channel activity, as well as histone H3T11 kinase activity. The gene is associated with transport of lactate, silicic acid, borate, arsenite and urea, and with cellular responses to boron, arsenic, glucose, hypoxia and defense regulation. It has been linked to seed development, seed weight, and localisation to the plasma membrane, Casparian strip, endoplasmic reticulum, cytoplasm and nucleus. Studies of related genes in other species connect the family to boron uptake and deficiency tolerance, arsenite and aluminum tolerance, arsenic distribution, pollen development, and traits including grain number, biomass yield, water use efficiency and salinity tolerance.
