The advances of NGS technologies and bioinformatics tools have opened opportunities to shed light on the diversity of microbial communities and to give some insights into the functions they perform in a broad array of hosts. The pea aphid is a model system for the study of insect-bacteria symbiosis. It is organized in a complex of biotypes, each adapted to specific host plants. It harbors both an obligatory symbiont supplying key nutrients and several facultative symbionts bringing additional functions to the host, such as protection against biotic and abiotic stresses. However, little is known on how the symbiont genomic diversity is structured Microbiome181https://www.ebi.ac.uk/biostudies/studies/S-EPMC6180509biostudies-literatureMulti-scale characterization of symbiont diversity in the pea aphid complex through metagenomic approaches.PMC6180509Lemaitre CGuyomar CLegeai FJousselin ESimon JCMougel CfalseMulti-scale characterization of symbiont diversity in the pea aphid complex through metagenomic approaches.<h4>Background</h4>Most metazoans are involved in durable relationships with microbes which can take several forms, from mutualism to parasitism.
