Abstract
In Plants, resistance genes (R genes) are generally a part of large gene families, which are known to show significant variation within and between different plant species. It has been hypothesised that R genes have evolved different specificities to recognize a wide range of potentially fast evolving pathogens. In this review we illustrate the main mechanisms that generate R gene diversity and provide examples of how they can change R gene specificity. Next, we explain which evolutionary mechanisms are in place and how they determine the fate of new R gene alleles and R genes. Finally, we place this in a larger context by comparing the diversity and evolution of R gene specificity on within and between species scales.
