Introduction and History
The World Phytophthora Collection (WPC) contains about 2000 isolates of over 160 species, collected from multiple plant hosts or aquatic environments around the world. Most isolates are Phytophthora, although a few other genera including Pythium are also represented.
The collection was founded by former department faculty D. C. Erwin and G. A. Zentmyer. Isolates from the collection have been used in several hundred scientific publications by researchers around the world studying topics such as plant pathology and evolution. The collection is currently co-curated by James Adaskaveg and Howard Judelson.
Isolates are currently maintained in liquid nitrogen, which allows for long-term storage. Click here to download a list of the isolates in the collection:
