The Diversification of Downy Mildew Species Was Not Driven by the Loss of Mycorrhizal Associations or the Evolution of C4 Photosynthesis

PhytoFrontiers, 2022
There are approximately 700 obligate biotrophic species grouped into 20 genera (Oomycota, Peronosporaceae) that cause downy mildew diseases. In 2001, Dick hypothesized that diversification of downy mildew species was driven in part by host plant ...
