Journal ArticleDOI
Persistence of the Mitochondrial Lineage Responsible for the Irish Potato Famine in Extant New World Phytophthora infestans
Michael D. Martin,Simon Y. W. Ho,Nathan Wales,Jean B. Ristaino,M. Thomas P. Gilbert,M. Thomas P. Gilbert +5 more
TL;DR: 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.
Journal ArticleDOI
Spatial dynamics of disease symptom expression during Phytophthora epidemics in bell pepper
TL;DR: Wilting preceded crown symptoms, suggesting that root infection and subsequent colonization to crowns of plants occurred most frequently, and two dimensional distance class analysis characterized spatial dynamics.
Journal ArticleDOI
Characterization of Isolates of Phytophthora infestans from Tomato and Potato in North Carolina from 1993 to 1995
TL;DR: The US-7 genotypes was more frequent on tomato in western North Carolina and the US-8 genotype was present on potato in eastern North Carolina, indicating that different inoculum sources are responsible for epidemics on the two crops in different regions of the state.
Journal ArticleDOI
Detection of Phytophthora infestans by Loop-Mediated Isothermal Amplification, Real-Time LAMP, and Droplet Digital PCR
TL;DR: The loop-mediated isothermal amplification (LAMP) assay was specific for P. infestans on potato and tomato and did not amplify other potato- or tomato-infecting Phytophthora species or other fungal and bacterial pathogens that infect potato and Tomato.
Journal ArticleDOI
Large sub-clonal variation in Phytophthora infestans from recent severe late blight epidemics in India.
Tanmoy Dey,Amanda C. Saville,Kevin Myers,Susanta Tewari,David E. L. Cooke,Sucheta Tripathy,Sucheta Tripathy,William E. Fry,Jean B. Ristaino,S. Roy +9 more
TL;DR: The population structure of the Phytophthora infestans populations that caused the recent 2013–14 late blight epidemic in eastern India and northeastern India was examined and suggested genetic contributions from UK and Europe in addition to a sub-structure based on the geographical location within India.
