1. The document discusses a bioinformatics project to catalog computationally putative resistance genes in grape and their corresponding pathogenicity genes. 2. The project searches databases to find main pathogenicity genes in pathogens and resistance genes in Arabidopsis thaliana, then catalogs them and uses BLAST to search for matches in grape genomes. 3. Examples show matches found between the rpfF gene in Xylella fastidiosa and the virB2 gene in Agrobacterium tumefaciens when BLASTed against grape genomes.
