Kobayasi Y, Hoekenga OA, Ito H, Nakashima M, Saito S, Shaff JE , Maron LG, Piñeros MA, Kochian LV, Koyama H. 2007. Characterization of AtALMT1 expression in aluminium inducible malate release and its role for rhizotoxic stress tolerance in Arabidopsis thaliana.  Plant Physiology 145: 843–852 (DOI:10.1104/pp.107.102335).

Malate transporters play a critical role in aluminium (Al) tolerance responses for some plant species, such as Arabidopsis (Arabidopsis thaliana). Here, we further characterize AtALMT1, an Arabidopsis aluminum-activated malate transporter, to clarify its specific role in malate release and Al stress responses. Malate excretion from the roots of accession Columbia was sharply induced by Al, which is concomitant with the induction of AtALMT1 gene expression.
