Insect heritable symbionts have proven to be ubiquitous, based on molecular screening of
various insect lineages. Recently, molecular and experimental approaches have yielded an …

Aphids engage in symbiotic associations with a diverse assemblage of heritable bacteria. In
addition to their obligate nutrient-provisioning symbiont, Buchnera aphidicola, aphids may …

Mutualistic organisms can be particularly susceptible to climate change stress, as their
survivorship is often limited by the most vulnerable partner. However, symbiotic plasticity can …

Throughout the natural world, organisms have responded to predators, inadequate
resources, or inclement conditions by forming ongoing mutually beneficial partnerships--or …

Color variation within populations of the pea aphid influences relative susceptibility to
predators and parasites. We have discovered that infection with a facultative endosymbiont …

Adaptive phenotypic plasticity provides a mechanism of developmental rescue in novel and
rapidly changing environments. Understanding the underlying mechanism of plasticity is …

In North America and Europe, the pea aphid (Acyrthosiphon pisum) encompasses
ecologically and genetically distinct host races, offering a model system for studies on …

Our understanding of prokaryote–eukaryote symbioses as a source of evolutionary
innovation has been rapidly increased by the advent of genomics, which has made possible …

Bacterial symbionts are widespread in insects and other animals. Most of them are
predominantly vertically transmitted, along with their hosts' genes, and thus extend the …

Symbiotic bacteria are important in animal hosts, but have been largely overlooked as they
have proved difficult to culture in the laboratory. Approaches such as comparative genomics …
