Panglobal distribution of a single clonal lineage of the Irish potato famine fungus.
More than 300 isolates of the Irish potato famine fungus, Phytophthora infestans, collected in 20 countries on five continents, were analyzed for genetic variation at the mating type and two allozyme loci. A subset of more than 200 isolates was also analyzed for DNA "fingerprint" variation. A surprising result was that a single clonal lineage dominated most populations worldwide. All of the var...
متن کاملThe rise and fall of the Phytophthora infestans lineage that triggered the Irish potato famine
Phytophthora infestans, the cause of potato late blight, is infamous for having triggered the Irish Great Famine in the 1840s. Until the late 1970s, P. infestans diversity outside of its Mexican center of origin was low, and one scenario held that a single strain, US-1, had dominated the global population for 150 years; this was later challenged based on DNA analysis of historical herbarium spe...
متن کاملGenome Analyses of an Aggressive and Invasive Lineage of the Irish Potato Famine Pathogen
Pest and pathogen losses jeopardise global food security and ever since the 19(th) century Irish famine, potato late blight has exemplified this threat. The causal oomycete pathogen, Phytophthora infestans, undergoes major population shifts in agricultural systems via the successive emergence and migration of asexual lineages. The phenotypic and genotypic bases of these selective sweeps are lar...
متن کاملAn effector of the Irish potato famine pathogen antagonizes a host autophagy cargo receptor
Plants use autophagy to safeguard against infectious diseases. However, how plant pathogens interfere with autophagy-related processes is unknown. Here, we show that PexRD54, an effector from the Irish potato famine pathogen Phytophthora infestans, binds host autophagy protein ATG8CL to stimulate autophagosome formation. PexRD54 depletes the autophagy cargo receptor Joka2 out of ATG8CL complexe...
متن کاملEffector specialization in a lineage of the Irish potato famine pathogen.
Accelerated gene evolution is a hallmark of pathogen adaptation following a host jump. Here, we describe the biochemical basis of adaptation and specialization of a plant pathogen effector after its colonization of a new host. Orthologous protease inhibitor effectors from the Irish potato famine pathogen, Phytophthora infestans, and its sister species, Phytophthora mirabilis, which is responsib...
