Abstract excerpt
Disease resistance (R) genes are often clustered in plant genomes and may exhibit heterogeneous rates of evolution. Some (type I R genes) have evolved rapidly through frequent sequence exchanges, while others (type II R genes) have evolved independently and tend to be conserved in different genotypes or related species. The RPP8 resistance gene in Arabidopsis thaliana is located at a complex locus that also...
