It is also important to point out that there are notable examples of pathogens that exhibit clear arms race dynamics and quantitative variation in virulence, but somehow infect phylogenetically unrelated plant species. These include Phytophthora capsici (pepper and cucurbits), Phytophthora palmivora (monocots and dicots), the multihost rust fungi and others. Even though these pathogens infect a phylogenetically discontinuous range of host plants, individual genotypes of their host species can exhibit classic strong genetic resistance. This context is important for the discussing the observation that variation in plant susceptibility does not track plant phylogeny.
