This data is based on the review by Catara (2021), focused on the molecular methods for diagnosis, detection, and studies on the diversity of plant pathogenic Xanthomonas, concentrating especially on regulated pathogens in the European Union published as a collective effort of the Working Group 1 'Diagnostics & Diversity–Population Structure' from the EuroXanth COST Action CA16107.
Diseases, their regulation and recommendations for management.
