Interpretive Summary:

Technical Abstract: Species of Phytophthora pose one of the most serious biosecurity threats to forest ecosystems worldwide. Despite management efforts and increased awareness of forest pathogens, the current research indicates continued introduction and spread of Phytophthora species. Uncertainty about the center of origin for many of the invasive species hampers control efforts. Additionally, the management efforts are often made impossible either by the vast host range or the extreme susceptibility of naïve hosts. In this review, we discuss how genomics has shed light on the extent of spread and destruction caused by invasive Phytophthora species, and how approaches leveraged by genomics can be applied to enhance the management of these invasive forest pathogens. We urge researchers, governmental research institutes, private companies, and citizens to collaborate in order to stop the forest devastation and the spread of invasive Phytophthora species. To accomplish this, we see the following themes as critical parts of resolving the forest health crisis: I) integration of DNA-based pathogen detection into forest inventory programs; II) development of practical and affordable DNA-based diagnostic methods; III) re-sequenced hosts as models for resistance gene identification; IV) prediction of pathogen impact based on genomic data; and V) increase collaborative projects and outreach to raise awareness of forest diseases.
