 This species has become a model organism from its ability to infect the model plant "Arabidopsis thaliana".It is used to study plant-pathogen interactions, and is currently the only "Hyaloperonospora" species that has an assembled genome.In 2002, "Hyaloperonospora" was discovered by Göker "et al"., who used molecular phylogenetic techniques to argue that the group was different enough from the other "Peronospora" species to be its own taxon.
