| Outline of Final Research Achievements |
Low pH and Al-responsive AtALMT1 (Arabidopsis Al-activated malate transporter1) regulates malate secretion from roots. In this study, we identified some compounds inhibiting malate secretion and AtALMT1 gene expression in screening of small molecule library used in drug discovery research. Additionally, among these compounds, a kinase inhibitor for phospholipid signaling inhibited expression of some Al-responsive genes and STOP1 nuclear localization. Furthermore, in silico docking study indicated that the inhibitor may bind the Arabidopsis homologue of target protein in human. These results strongly suggested that phospholipid signaling play an important role in Al signaling.
