ALMT1 — Triticum aestivum

Summary

TRAESCS4D02G283600 (symbol ALMT1, TaALMT1-4D) on bread wheat chromosome 4D encodes an ALMT-family protein with malate transmembrane transporter activity. In wheat, ALMT1 is directly associated with aluminium resistance, acid-soil tolerance, and grain yield. The gene is associated with organic acid transport, malate and citrate secretion, GABA transport, nectar secretion, stomatal opening, root system development, and responses to aluminium and iron. It localises to the tonoplast, plasmalemma, and nucleus. Associations also include acid soil tolerance, grain dormancy, spikelet density, stem and stripe rust, phosphorus uptake, root volume and hair length, heading time, grain length, sugar content, and ear number. Related genes in other species are linked to aluminium-activated malate transport, aluminium tolerance, phosphorus acquisition, root development under phosphate starvation, plant immunity, and beneficial bacteria recruitment.
