Oospores progenies from Phytophthora ramorum

Fungal Biology, 2010
Oospores of Phytophthora ramorum were produced from intraspecific pairings between a European A1 and European or American A2 strains. Their viability was evaluated through colouration with tetrazolium bromide. The distribution of oospores in the different classes of colouration was similar to that found in other Phytophthora species (homothallic and ...

Incidence of endornaviruses in Phytophthora taxon douglasfir and Phytophthora ramorum

Virus Genes, 2009
In this investigation, we show that four Phytophthora taxon douglasfir isolates from the USA, irrespective of their geographical location or host plant, and 20% of a representative cohort of Phytophthora ramorum isolates contain endornavirus dsRNAs. Three endornavirus-specific RT-PCR amplicons were generated by RT-PCR using dsRNA isolated from the four

Production of gametangia by Phytophthora ramorum in vitro

Mycological Research, 2004
Until now gametangia have not been obtained between paired European A1 and American A2 isolates of Phytopthora ramorum in vitro. Their production in artificial culture relies on interspecific pairings. Using P. drechsleri and P. cambivora testers, 51 of 110 P.

Emergence of the sudden oak death pathogen Phytophthora ramorum

Trends in Microbiology, 2012
The recently emerged plant pathogen Phytophthora ramorum is responsible for causing the sudden oak death epidemic. This review documents the emergence of P. ramorum based on evolutionary and population genetic analyses. Currently infection by P. ramorum occurs only in Europe and North America and three clonal lineages are distinguished: EU1, NA1 and ...
