Although many studies provide examples of evolutionary processes such as adaptive
evolution, balancing selection, deleterious variation and genetic drift, the relative importance …

We review current ideas about coevolution of plants and parasites, particularly processes
that generate genetic diversity. Frequencies of host resistance and parasite virulence alleles …

What is the nature of the genetic changes underlying phenotypic evolution? We have
catalogued 1008 alleles described in the literature that cause phenotypic differences among …

Many genome-wide association studies (GWAS) in humans are concluding that, even with
very large sample sizes and high marker densities, most of the genetic basis of complex …

Amino acid substitutions in the eukaryotic translation initiation factor 4E (eIF4E) result in
recessive resistance to potyviruses in a range of plant species, including Capsicum spp …

Highlights•Pathogen virulence and plant resistance genes are among the most variable
genes.•Selection on resistance alleles tends to be diversifying or balancing.•It is unclear …

To respond to pathogen attack, selection and associated evolution has led to the creation of
plant immune system that are a highly effective and inducible defense system. Central to this …

The plant group Solanum section Lycopersicon (the clade containing the domesticated
tomato and its wild relatives) is ideal for integrating genomic tools and approaches into …

Specificity in plant–pathogen gene‐for‐gene (GFG) interactions is determined by the
recognition of pathogen proteins by the products of plant resistance (R) genes. The …

Nucleotide binding site, leucine‐rich repeat receptors (NLR s) are canonical resistance (R)
genes in plants, fungi and animals, functioning as central (helper) and peripheral (sensor) …
