TL;DR: It is demonstrated that a clear picture of the evolutionary potential of parasitic organisms and their demographic and evolutionary histories can only come from understanding the role of life history and spatial structure in influencing population dynamics and epidemiological patterns.

TL;DR: This work identifies a naturally interacting R gene and effector pair in Arabidopsis thaliana and its facultative plant pathogen, Pseudomonas syringae and finds evidence that selection for RPS5 involves multiple non-homologous effectors and multiple pathogen species.

TL;DR: Cross-year epidemiological, infection and genetic studies of multiple wild host and pathogen populations in the Linum-Melampsora association show changes in allelic frequencies at pathogen infectivity loci, and in host recognition of these genetic variants, correlated with disease prevalence during natural epidemics, suggesting reciprocal coevolution maintaining balanced resistance and infectivity polymorphisms.

TL;DR: These continua of specificity and virulence inherent within plant host-pathogen interactions are described and compared to outline consequences for epidemiology and community structure, explore likely ecological and evolutionary drivers, and highlight several key areas for future research.

TL;DR: In this paper, the authors summarize patterns and mechanisms in the interactions of plants with these enemies along different axes of specificity and highlight the many dimensions within which plant enemies can specify and consider the underlying ecological, evolutionary and molecular mechanisms.
