Pathogen population genetics, evolutionary potential, and durable resistance.
TLDR
A flexible framework to predict the evolutionary potential of pathogen populations based on analysis of their genetic structure is proposed and pathogens that pose the greatest risk of breaking down resistance genes have a mixed reproduction system, a high potential for genotype flow, large effective population sizes, and high mutation rates.

Gene Flow in Plant Pathosystems
TLDR
The role of the temporal and spatial movement of genes and genotypes on the population dynamics and evolution of plant pathogenic fungi is considered.

Two new species
TLDR
Phylogenetic analyses of multilocus DNA sequence data on R. secalis isolates originating from cultivated barley, rye, triticale and other grasses, including Agropyron spp.
The population genetics of plant pathogens and breeding strategies for durable resistance
TLDR
A set of guidelines to predict the evolutionary potential of pathogen populations based on analysis of their genetic structure are proposed, suggesting a rational method for breeding durable resistance according to the population genetics of the pathogen.

Emergence of a new disease as a result of interspecific virulence gene transfer
TLDR
Evidence that a gene encoding a critical virulence factor was transferred from one species of fungal pathogen to another probably occurred just before 1941, creating a pathogen population with significantly enhanced virulence and leading to the emergence of a new damaging disease of wheat.

The origins of plant pathogens in agro-ecosystems.
TLDR
It is concluded that agro-ecosystems will continue to select for new pathogens unless they are re-engineered to make them less conducive to pathogen emergence.

The population genetics of fungi: tools and techniques.
TLDR
The purpose of this paper is to provide an overview of the tools and techniques of fungal population genetics and to try to emphasize approaches that may be applied to studies of soilborne fungi.

Population Structure of Mycosphaerella graminicola: From Lesions to Continents.
TLDR
The possibility of high levels of gene flow on a regional level indicates a significant potential risk for the regional spread of mutant alleles that enable fungicide resistance or the breakdown of resistance genes.
View on PubMed
The global genetic structure of the wheat pathogen Mycosphaerella graminicola is characterized by high nuclear diversity, low mitochondrial diversity, regular recombination, and gene flow.

Dothideomycete–Plant Interactions Illuminated by Genome Sequencing and EST Analysis of the Wheat Pathogen Stagonospora nodorum[W][OA]
TLDR
Statistical analysis shows that transcripts encoding proteins involved in protein synthesis and in the production of extracellular proteases, cellulases, and xylanases predominate in the infection library, suggesting that the fungus is dependant on the degradation of wheat macromolecular constituents to provide the carbon skeletons and energy for the synthesis of proteins and other components destined for the developing pycnidiospores.
