EVOGENE Seminar: Pierre Gladieux - Disease emergence and pathogen speciation

Pierre Gladieux is a research scientist at UMR BGPI, INRA Montpellier, France and he will give a talk entitled "Disease emergence and pathogen speciation".

Abstract: Emerging fungal diseases of plants represent a growing issue accompanying global environmental changes, and there is tremendous interest in identifying the factors controlling their appearance and spread. Theoretical and empirical work suggest that certain life-history traits of many fungal plant pathogens may favour rapid ecological speciation, thus promoting the emergence of novel pathogen species adapted to new hosts. We use the multihost fungal pathogen Magnaporthe oryzae as a model to investigate the proximate (i.e. molecular) and ultimate (i.e. eco-evolutionary) determinants of disease emergence. I will present our most recent work, combining population genomic analyses, in vitro crosses, and pathogenicity tests, to characterise the existence of reproductive isolation between the different lineages identified within Magnaporthe oryzae and to understand how they evolved.
