Standardizing the nomenclature for clonal lineages of the sudden oak death pathogen, Phytophthora ramorum. Phytopathology. 99:792-795.

Interpretive Summary: Phytophthora ramorum is the microorganism causing the sudden oak death and ramorum blight diseases. This pathogen exists as three distinct clones based on a range of molecular tools. However, in the recent literature there exists no consensus on naming of clones. Here we name clones of P. ramorum based on a consensus established by the P. ramorum research community at large. Clones are herewith designated NA1 (mating type A2; North America; forest and nurseries), NA2 (A2; North America; nurseries), and EU1 (predominantly A1, rarely A2; EU and North America; nurseries and gardens). These clones can only be distinguished using molecular tools.

Technical Abstract: Phytophthora ramorum, the causal agent of sudden oak death and ramorum blight, is known to exist as three distinct clonal lineages based on a range of molecular marker systems. However, in the recent literature there exists no consensus on naming of lineages. Here we name clonal lineages of P. ramorum based on a consensus established by the P. ramorum research community at large. Clonal lineages are herewith designated NA1 (mating type A2; North America; forest and nurseries), NA2 (A2; North America; nurseries), and EU1 (predominantly A1, rarely A2; EU and North America; nurseries and gardens). These clonal lineages can best be distinguished by performing either mitochondrial or microsatellite analyses.
