Pathogen population genetics, evolutionary potential, and durable resistance.
We hypothesize that the evolutionary potential of a pathogen population is reflected in its population genetic structure. Pathogen populations with a high evolutionary potential are more likely to… Expand
Gene Flow in Plant Pathosystems
The idea that theory developed in the fields of population genetics and evolutionary biology can be used to investigate and understand problems in plant pathology has not been widely accepted. Today,… Expand
Two new species
Rhynchosporium consists of two species, R. secalis and orthosporum. Both are pathogens of grasses with R. secalis infecting a variety of Poaceae hosts and R. orthosporum infecting Dactylis glomerata.… Expand
The population genetics of plant pathogens and breeding strategies for durable resistance
The durability of disease resistance is affected by the evolutionary potential of the pathogen population. Pathogens with a high evolutionary potential are more likely to overcome genetic resistance… Expand
Emergence of a new disease as a result of interspecific virulence gene transfer
New diseases of humans, animals and plants emerge regularly. Enhanced virulence on a new host can be facilitated by the acquisition of novel virulence factors. Interspecific gene transfer is known to… Expand
The origins of plant pathogens in agro-ecosystems.
Plant pathogens can emerge in agricultural ecosystems through several mechanisms, including host-tracking, host jumps, hybridization and horizontal gene transfer. High-throughput DNA sequencing… Expand
Population Structure of Mycosphaerella graminicola: From Lesions to Continents.
ABSTRACT The genetic structure of field populations of Mycosphaerella graminicola was determined across a hierarchy of spatial scales using restriction fragment length polymorphism markers. The… Expand
The population genetics of fungi: tools and techniques.
Over the last 10 years plant pathologists have begun to realize that more knowledge about the genetic structure of populations of plant pathogens is needed to implement effective control strategies… Expand
The global genetic structure of the wheat pathogen Mycosphaerella graminicola is characterized by high nuclear diversity, low mitochondrial diversity, regular recombination, and gene flow.
A total of 1673 Mycosphaerella graminicola strains were assayed for DNA fingerprints and restriction fragment length polymorphism (RFLP) markers in the nuclear and mitochondrial genomes. The isolates… Expand
Dothideomycete–Plant Interactions Illuminated by Genome Sequencing and EST Analysis of the Wheat Pathogen Stagonospora nodorum[W][OA]
Stagonospora nodorum is a major necrotrophic fungal pathogen of wheat (Triticum aestivum) and a member of the Dothideomycetes, a large fungal taxon that includes many important plant pathogens… Expand
