Title: Living with Intracellular Bacteria

Abstract: Many insects harbor beneficial intracellular bacteria that provide nutrients or enhance resistance to natural enemies, but the molecular basis of these apparently harmonious associations is poorly understood. Using plant sap-feeding insects as examples, I will discuss our recent research on nutrient exchange between the insect host cell and intracellular bacteria with very small genomes. Using a combination of genomic and metabolic approaches, we have identified the nutrients transferred between the partners and how nutrient flux is regulated. These associations display metabolic coevolution, involving metabolic pathways shared between host and bacteria, as well as instances of bacterial genes transferred to the insect genome; and they provide candidate targets for novel insect pest control strategies based on the insect dependence on their microbial partners.
