ALMT1 — Triticum aestivum

Summary

TRAESCS2D02G295900, designated TaALMT1 on wheat chromosome 2D, encodes an ALMT-family protein with malate transmembrane transporter activity. The gene is associated with aluminium resistance and acid-soil tolerance in bread wheat, and is linked to grain yield. It is associated with organic acid and malate membrane transport, GABA transport, ion membrane transport, pH reduction, and the response to aluminium. Localisation evidence places the product at the tonoplast, plasmalemma, and nucleus. Additional associations include phosphorus uptake, root hair length, tiller and ear number, plant height, anthesis time, proline content, and meristem identity. The gene has also been connected to stomatal closure, defence response, root system architecture, malate secretion and exudation, aluminium exclusion, and rhizobacteria recruitment. Related genes in other species are linked to aluminium tolerance, phosphorus acquisition, plant immunity, and root elongation under phosphate starvation.
