Abstract

PCR-mediated gene shuffling is a powerful technique for generating chimeras that combine useful mutations from individual genes. The tomato Cf-4 and Cf-9 genes and their homologues (Hcr9s) will be shuffled using an error-prone DNA polymerase. This process will mimic in vitro the natural mechanisms that generate novel recognition specificities in this R gene class but at a vastly accelerated rate. Libraries of recombinant Hcr9s will be tested in high throughput transient expression assays for their ability to recognise defined C. fulvum extracellular proteins (ECPs) and to induce a hypersensitive response. This will determine the feasibility of creating synthetic plant resistance genes and is important to the goal of engineering durable resistance in crop plants.
