The biology of many animals is partly defined by the microbes with which they interact – digestion, immunity, physiology and behaviour are all impacted by microbial partners. These symbioses are most intimate in insects, where the microbes are commonly passed between mother and progeny, in or on eggs. This vertical transmission makes the symbiont an integral – and in some cases essential - part of the host’s biology.
These symbioses are biologically interesting – but also have applied importance. Symbionts can alter important aspects of host biology – such as insect vector competence – and thus be deployed in the field to improve human and plant health. They may also represent ‘weak links’ in organisms that can be targeted – as in control of filarial infections through targeting their required symbiont.
In this project, we will characterize the symbiosis between a gammaproteobacterial symbiont – Symbiopectobacterium purcellii – and hemipteran (plant sap-sucking) bugs. We aim to understand how the symbiont establishes in its insect host, how it impacts on host biology, and how it affects the interaction between insect and plant. Subsequently, we will address wider questions: Does the bacterium travel through the plant? Does it cause plant damage or affect plant resilience to stress? Does it potentiate or inhibit the transmission of other pathogens from bug to plant?
You will work between the insect symbiosis group in Liverpool and the insect-plant interaction group in Newcastle. You’ll receive training in experimental analysis of insect-microbe and insect-plant interactions, molecular microbiology, molecular biology, statistical analysis, and genomics/transcriptomic approaches. You will work in an Open Science environment, promoting the reproducibility of research and the reuse of data. You will also benefit from public and stakeholder engagement activities.
We welcome applications from students with an interest in entomology, microbiology, crop sciences. The most important attribute is the desire to be able to work with all aspects of the interaction – microbe, insect and plant.
