Biological and molecular evidences about changes in the host range and virulence of Pseudoperonospora cubensis populations in the Czech Republic
Original language description
During the 2009-2012 growing seasons, disease prevalence and severity and the host range of P. cubensis were evaluated at more than 80 locations in the Czech Republic (CR). Infection by P. cubensis was observed primarily on Cucumis sativus, medium to high disease severity prevailed. During the years 2010 - 2012, P. cubensis infection was also frequently recorded on other cucurbit plants: Cucumis melo, Citrullus lanatus, Cucurbita spp. (C. moschata, C. pepo, C. maxima, C. ficifolia) and Lagenaria siceraria. P. cubensis infection on C. moschata and some other Cucurbita spp. was observed for the first time in the CR. Virulence shift (2009-2012) was studied in populations of 95 P. cubensis isolates. We observed substantial changes in the pathogen population virulence structure - from 2009 onwards. AFLP procedure and multilocus sequence analysis (MLSA) of six mitochondrial and nuclear DNA regions were used to detect changes in the genetic structure of P. cubensis populations. The analysed s
