ALMT1 (TRAESCS2A02G297900) — triticum aestivum

Summary

TRAESCS2A02G297900, the wheat gene TaALMT1 on chromosome 2A, encodes an aluminum-activated malate transporter belonging to the ALMT family. The gene product exhibits malate transmembrane transporter activity and is associated with organic acid transport, malate membrane transport, GABA transport, and ion membrane transport. TaALMT1 is linked to aluminium resistance and acid-soil tolerance in bread wheat, and has been connected to grain yield. The transporter localises to the tonoplast, plasmalemma, and nucleus, and is associated with processes including pH reduction, response to aluminum, detoxification, and ethylene anabolism. Additional associations include root growth under metal stress, malate secretion and exudation, aluminum exclusion, phosphate starvation response, stomatal closure, and rhizobacteria recruitment. Related genes in other species link the family to aluminum tolerance, phosphorus acquisition, and plant immunity.
