| Outline of Final Research Achievements |
In this study, two tomato ALMT-family malate transporter genes expressed in fruit and leaf were analyzed. The SlALMT gene in fruit was found to be expressed in the vascular bundles during the early stage of maturation. The SlALMT transporter exhibited the efflux of malate as well as dicarboxylic acids, and the influx of nitrate and chloride. The transgenic suppresser were constructed and examined several metabolites. Malate content in mature green fruit was not different between wild type and the suppressor lines. The SlALMT gene in leaf was found to be expressed in guard cells. The SlALMT transporter exhibited the malate-efflux activated by extracellular malate concentration.
