Fitness characteristics of the European lineages of Phytophthora ramorum
Plant Pathology, 2020Abstract As an introduced pathogen, Phytophthora ramorum exists as four near‐clonal evolutionary lineages, of which only EU1 and EU2 are established in the UK. EU1 has become widespread since the first findings in 2002 whereas EU2, detected in 2011, has a more limited ...

Phytophthora ramorum, the cause of sudden oak death or ramorum leaf blight and dieback
Mycologist, 2004In 1993, a new species of Phytophthora was first recognised as the cause of a disease killing both nursery and mature rhododendrons in Germany and The Netherlands. The same fungus was observed attacking Viburnum in 1998 in Germany. It was named as P. ramorum in 2001 (Werres et al ., 2001).

Discovery of a fourth evolutionary lineage of Phytophthora ramorum: EU2
Fungal Biology, 2012Phytophthora ramorum is a recently introduced, aggressive Phytophthora species that has caused extensive mortality of oak and tanoak trees in the western USA and Japanese larch trees in the UK. P. ramorum is also present on Rhododendron, Camellia, and Viburnum in the nursery industry, which is thought to have been the pathway for its spread into new ...

Antimicrobial Activity of Extractable Conifer Heartwood Compounds Toward Phytophthora ramorum
Journal of Chemical Ecology, 2007Ethyl acetate extracts from heartwood of seven western conifer trees and individual volatile compounds in the extracts were tested for antimicrobial activity against Phytophthora ramorum. Extracts from incense and western redcedar exhibited the strongest activity, followed by yellow-cedar, western juniper, and Port-Orford-cedar with moderate activity ...

Aberrant genome size and instability of Phytophthora ramorum oospore progenies
Fungal Genetics and Biology, 2011The functionality of the sexual cycle in the heterothallic pathogen Phytophthora ramorum, causal agent of Sudden Oak Death, has recently been demonstrated. Sexual reproduction could create genotypic variation and increase the pathogen's ability to adapt to other host plants or changing environments.

Phytophthora ramorum and Phytophthora kernoviae: the woodland perspective
EPPO Bulletin, 2009Phytophthora ramorum and P. kernoviae were first identified in Great Britain (GB) in 2002 and 2003 respectively, although both are believed to have been present for perhaps 10–20 years. Public gardens have been badly affected by these pathogens, but British woodlands are also considered at risk as a number of tree species have been found to be ...

Mitochondrial haplotype determination in the oomycete plant pathogen Phytophthora ramorum
Current Genetics, 2008The mitochondrial genome of an isolate of Phytophthora ramorum from Europe (EU) was sequenced and compared to the previously published genome sequence of an isolate from California (NA). The EU mitochondrial genome had the identical gene order and encoded for the same suite of genes as the NA mitochondrial genome, but had 13 single nucleotide ...
