| Research Abstract |
Bacterial wilt is caused by a soil borne pathogen. When infected with incompatible strain into plant leaves, development of the leaf trachea were inhibited and UV fluorescence microscopy of infected sections showed the accumulation of fluorescence substances around the leaf vein. In this research, we studied changes in metabolic profiles at the infection sites of eggplants challenged by during the infection of an incompatible-strain, through the metabolome analyses. From the relation between inoculum strain and disease resistance, two different mechanisms are found for the resistance, 1); the production of compounds involved in the elongation arrest vein to accumulate at the site of infection, and 2); antimicrobial compound that inhibits the growth of bacteria.
