Sudden oak death mortality of tanoak in Marin County, California.
Sudden oak death, caused by the fungus-like pathogen Phytophthora ramorum, has caused devastating levels of mortality of live oak and tanoak trees in coastal California. It also infects popular ornamental plants, and the shipment of diseased plants from West Coast wholesale nurseries has risked introduction to other vulnerable forests. Goss et al. examined the genetic diversity of this pathogen in US nurseries and found that there are two predominant eastward migration pathways originating from the West, in either California or the Pacific Northwest. This work has implications for management of sudden oak death (see Goss et al., doi:10.1371/journal.ppat.1000583).
