AM25 — Brachypodium distachyon

Summary

BdAM25 (BRADI_3G30540V3) on chromosome 3 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 localisation at the lateral plasma membrane, peribacteroid membrane, Casparian strip, ER and cytoplasm. Associations include 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 boron content, arsenic accumulation, silicon transport, salt and drought responses, and grain number.
