This study examines the evolutionary dynamics of two symbiotic bacteria in aphids, showing they evolve together with similar rates and undergo functional specialization.

The paper identifies barrier loci across a divergence continuum in pea aphids, showing their clustering in low-recombination regions and enrichment for genes related to host specialization.

This study analyzes discordant phylogenomic data from aphids to resolve their evolutionary history, finding monophyly of subfamilies but unresolved relationships between them.

The paper shows that dual symbioses have evolved at least six times in aphids, with secondary co-obligate symbionts typically evolving from facultative taxa and varying in nutrient contributions.

The paper analyzes APSE phage genomes from Hamiltonella symbionts in aphids, revealing recombination events and variable toxin regions.

The paper investigates horizontal gene transfer in aphid symbionts, showing how B-vitamin biosynthesis genes are transferred between bacteria to establish new nutritional symbioses.

The paper identifies a third bacterial symbiont in Cinara strobi aphids and shows that S. symbiotica has a highly eroded genome, suggesting ongoing symbiont replacement.
