Editing of Susceptibility Genes (S-genes)
Late blight (LB), caused by Phytophthora infestans, and powdery mildew (PM), caused by species within the Erysiphaceae family, are the most destructive and widespread diseases in tomato (Solanum lycopersicum L.). The control of these pathogens extensively relies on fungicide application, leading to economic losses and environment impact.
The disabling of susceptibility (S) genes, which facilitate pathogen infection, may provide a broad-spectrum and durable type of resistance. To this purpose, the CRISPR/Cas9 gene editing represents the most suitable and fast strategy.
We selected the Powdery Mildew Resistant 4 (PMR4) and Downy Mildew Resistant 6 (PMR4) genes, whose disabling has been shown previously observd to confer PM/DM resistance in other species.
Our results will provide suitable tools for biotechnological applications and open the way to the development of pathogen resistant tomato genotypes.
