eLife assessment
This important study reveals the molecular basis of mutualism between a vector insect and a bacterium responsible for the most devastating disease in citrus agriculture worldwide. The evidence supporting the conclusions is compelling, with biochemical and gene expression analysis demonstrating the phenomenon. However, there are concerns related to the presentation, as well as lack of sufficient information about data analysis, both of which should be clarified and/or extended. With these matters addressed, this work will be of great interest to the fields of vector-borne disease control and host-pathogen interaction.
