Interpretive Summary:

Technical Abstract: Two of the most important emerging diseases in the US, Huanglongbing (HLB) (also referred to as Citrus Greening Disease) and Zebra Chip of potato (ZC), are caused by bacterial pathogens that are spread by psyllids. These diseases are both associated with infection by species of the plant-infecting bacteria Candidatus Liberibacter. Glutathione S-transferases (GST) enzymes are involved in the detoxification of stress-causing agents associated with resistance to insecticides and response to microorganisms. To better understand the relationships between bacterium and psyllid, we identified and compared transcripts encoding GST members from the two insects spreading these diseases: the Asian citrus psyllid and the potato psyllid, responsible for the transmission of HLB and ZC respectively. The genetic basis for the development of insecticide resistance appears to be similar between these two psyllid species. We report on the identification and comparison of GSTs members in both psyllid species.
