The study examined the evolutionary relationship between powdery mildew species in the Golovinomyces genus and their hosts in the Asteraceae plant family. It found that Golovinomyces growing on Heliantheae plants formed a distinct lineage including three species, but also included specimens from other Asteraceae tribes and plant families, indicating a plurivorous species. The researchers used multiple DNA data sets to clarify discrepancies between previous studies and updated the classification and host ranges of the species.
