Liberibacter solanacearum” is a pathogen transmitted by the potato psyllid
(Šulc) (Hemiptera: Triozidae) in a persistent manner. In this study, we investigated the molecular interaction between “
Liberibacter solanacearum” and the potato psyllid at the gut interface. Specifically, we focused on the apoptotic response of potato psyllids to the infection by two “
Liberibacter solanacearum” haplotypes, LsoA and LsoB.
