The paper analyzes the Thermococcales pangenome to identify new genera and reveal modular evolution through horizontal gene transfer.

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 analyzes microbial diversity in French PDO cheeses using metagenomics and culturomics, identifying new species and functional clusters that may influence cheese flavor.

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 reports higher gene counts in two coral genomes due to tandem duplications, suggesting a role in immune system and disease resistance.

This paper evaluates Oxford Nanopore and Bionano Genomics technologies for detecting structural variations in Arabidopsis thaliana, finding that ONT provides more specific SVs while Bionano better characterizes large SVs.

The paper shows symbiotic bracovirus genes have spread to all chromosomes of parasitoid wasps and are stably maintained, with synchronized expression and no immune response.

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.

This paper develops a high-throughput method to map DNA replication at the single-molecule level using an optical mapping system.

The paper models metabolic interactions among bacterial symbionts in whiteflies to understand their dependencies and exchanges in a host-simulated environment.
