AM25 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0296150, designated HvAM25 on barley chromosome 3H, encodes an aquaporin-like protein with transmembrane transporter activities for lactate, arsenite, glycerol, borate, urea and water, and is annotated with histone H3T11 kinase activity and protein binding. The gene is associated with membrane transport of boron, arsenite, urea and hydrogen peroxide, and with responses to boron, arsenic, hypoxia, glucose and defense. It has been linked to boron uptake and deficiency tolerance, arsenite tolerance and uptake, aluminum tolerance and translocation, urea uptake, and pollen development and pollination. Related genes in other species are associated with arsenic accumulation and distribution, silicon transport, salt stress, reproductive development, and traits including grain number, seed weight, biomass yield, water use efficiency and tiller number.
