Phytophthora ramorum: Interactive mapping of findings in U.S. nurseries
The pathogen Phytophthora ramorum, known to cause sudden oak death on the West coast of the U.S., occurs in North America as three distinct clonal lineages . Here we present a map of the occurrence of the pathogen P. ramorum in U.S. nurseries. The map can be set to display observations by clonal lineage. We use a method called microsatellites (or simple sequence repeats) to place P. ramorum individuals into one of four currently globally recognized clonal lineages named NA1, NA2, EU1, and EU2 . The EU2 lineage has not been observed in the U.S.
