The theme of the conference is: Confronting the Phloem-Colonizing Bacterial Pathosystems Together

The conference will focus on diagnostics, epidemiology, omics (genomics, transcriptomics, proteomics, or metabolomics), pathogen and plant interactions, pathogen and insect interactions, pathogen biology, insect and plant interactions, insect biology, plant defense, biotechnology and disease control of the pathosystems caused by the phloem-colonizing bacterial pathogens caused by Candidatus Liberibacter, Candidatus Phytoplasma, and Spiroplasma.
