Persistence of the mitochondrial lineage responsible for the Irish potato famine in extant new world phytophthora infestans.
Ph phylogenetic analyses are used to identify the HERB-1 lineage in modern populations from both Mexico and South America, and to demonstrate distinct mitochondrial haplotypes were present in 19th-century Europe, with this lineage initially diversifying 75 years before the first reports of potato late blight.
Mining Herbaria for Plant Pathogen Genomes: Back to the Future
How whole genome analysis of ancient DNA has been recently used to reconstruct the 19th-century potato-blight epidemic that rapidly spread throughout Europe and triggered the Irish potato famine is summarized.
Crop health and its global impacts on the components of food security
The literature on the importance of plant pathogens sometimes emphasizes their possible role in historical food shortages and even in famines. Aside from such major crises, plant pathogens should
Evidence for presence of the founder Ia mtDNA haplotype of Phytophthora infestans in 19th century potato tubers from the Rothamsted archives
The founder Ia mtDNA haplotype survived in potato tubers after 1846 and was present over 30 years later in the UK, thus providing the earliest evidence of the presence of the founder IA mt DNA haplotype of P. infestans in Potato tubers in England.
Genomics Meets Biodiversity: Advances in Molecular Marker Development and Their Applications in Plant Genetic Diversity Assessment
The precise detection of genetic variation/diversity has greatly enhanced studies of evolution and is a key element in the early concepts and models of population ecology, genetics and adaptive evolution.
The occurrence of the A2 mating type of Phytophthora infestans in the Netherlands; significance and consequences
The significance of the presence of A1 and A2 mating type isolates in the Netherlands is reviewed and sexual reproduction can occur and its consequences for the control of potato late blight are discussed.
Aerial Dispersal and Multiple-Scale Spread of Epidemic Disease
A simple model of disease spread that incorporates logistic growth in time with an inverse power function for dispersal improves understanding of the geographic spread of emerging diseases, and facilitates the development of methods for predicting and preventing epidemics of plants, animals, and humans caused by pathogens that are capable of long-distance dispersal.
Adaptation to the most abundant host genotype in an agricultural plant–pathogen system – potato late blight
These observations support the theoretical predictions that large pathogen dispersal rates and genetic drift can lead to a local adaptation pattern detectable only at a large spatial scale and the unravelling of adaptive patterns at different spatial scales can be used for a more efficient management of the disease.
The population genetics of plant pathogens and breeding strategies for durable resistance
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.
