Journal ArticleDOI
Historic Late Blight Outbreaks Caused by a Widespread Dominant Lineage of Phytophthora infestans (Mont.) de Bary.
TL;DR: The FAM-1 SSR lineage survived for almost 100 years in the US, was geographically widespread, and was displaced first in the mid-20th century by the US-1 lineage and then by distinct new aggressive lineages that migrated from Mexico.
Journal ArticleDOI
Genetic structure of Phytophthora infestans populations in China indicates multiple migration events.
TL;DR: MtDNA haplotype evidence and RFLP data suggest multiple migrations of the pathogen into China after the initial introduction of the Ia haplotype in the 1930s.

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.

Large sub-clonal variation in Phytophthora infestans from recent severe late blight epidemics in India.

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.
Journal ArticleDOI
Evidence for presence of the founder Ia mtDNA haplotype of Phytophthora infestans in 19th century potato tubers from the Rothamsted archives
TL;DR: 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.
