AM25 — Sorghum bicolor

Summary

SbAM25 (SORBI_3007G039500) on sorghum chromosome 7 encodes an aquaporin-like protein with channel activity, including water, glycerol, urea, borate, arsenite and lactate transmembrane transporter activities, and is associated with histone H3T11 kinase activity and protein binding. The gene is linked to transport of boron, arsenite, urea and lactate, as well as responses to boron, arsenic, hypoxia and glucose, and regulation of defense response and phenylpropanoid metabolism. It localizes to the plasma membrane, ER, cytoplasm and nucleus. Associations include boron uptake and deficiency tolerance, arsenite and aluminum tolerance, aluminum translocation, urea uptake, and pollen development and pollination. Related genes in other species are linked to arsenic accumulation, silicon transport, salt stress, reproductive development, and traits such as seed weight, grain number, biomass yield, water use efficiency and flowering time.
