Putting 'X' into Context: The Diversity of ' Phytoplasma pruni' Strains Associated with the Induction of X-Disease.

Recurrent epiphytotics of X-disease, caused by ' Phytoplasma pruni,' have inflicted significant losses on commercial cherry and peach production across North America in the last century. During this period, there have been multiple studies reporting different disease phenotypes and, more recently, identifying different strains through sequencing core genes, but the symptoms have not, to date, been linked with genotype. Therefore, in this study we collected and assessed differing disease phenotypes from multiple U.
