ALMT1 (TRAESCS2B02G314100) — triticum aestivum

Summary

TRAESCS2B02G314100, designated TaALMT1 on wheat chromosome 2B, encodes a member of the ALMT family and has malate transmembrane transporter activity. In bread wheat, TaALMT1 is associated with aluminium resistance, acid-soil tolerance, and grain yield. The gene is associated with organic acid transport, malate membrane transport, GABA transport, and response to aluminium, with the protein localising to the tonoplast, plasmalemma, and nucleus. Additional associations include acid soil sensitivity, phosphorus uptake, root hair length, tiller number, grain weight, and plant height. TaALMT1 is also linked to malate secretion, aluminium exclusion, root growth under metal stress, stomatal closure, phosphate starvation response, and rhizobacteria recruitment. Studies of related genes in other species connect the family to aluminium tolerance, phosphorus acquisition, plant immunity, and root development under phosphate starvation.
