Characterization of Resistance to Pseudomonas syringae pv. tomato in Tomato
We developed a high-throughput seedling flood assay to identify wild species of tomato that are resistant against Pseudomonas syringae, a bacterial pathogen that causes disease in a broad range of plant species. The screen identified multiple accessions of wild tomato with varying degrees of resistance to the pathogen. We are characterizing and mapping the resistance phenotype in lines of interest, in order to identify the causative genes. Our work will identify new sources of genetic resistance to the plant pathogen in tomato.
