Abstract
Purpose of Review
Host-associated microbiomes can play key roles in the health of animals and plants, but fundamental aspects of the dynamics and evolution of microbial communities are not fully understood.
Recent Findings
Several recent studies have sequenced and analyzed the entire diversity of microbial species and strains in different host-associated microbiomes. These studies analyze the population genetics of host-associated microbes, yet many questions remain unanswered.
Summary
In this review, we describe the key insights that have been gained by recent microbiome population genetics studies and how they have contributed to our understanding of the fundamental mechanisms that alter the population dynamics of entire microbial communities. We further discuss the technical limitations of current approaches and how new methods and model systems would allow for better genetic characterization of host-associated microbiome populations.

Nat Commun. 2019;10:446. https://doi.org/10.1038/s41467-019-08303-0 Authors use shotgun metagenomics to access strain diversity within the bee gut and find that each honey bee harbors a distinct community at the functional level. Findings highlight the need to move beyond phylotype-level characterizations to understand the function, and illustrates the potential for using the honey bee as a model system for strain-level analysis.

PLoS Biol. 2017;15:e2003467. https://doi.org/10.1371/journal.pbio.2003467 This study used untargeted metabolomics to profiled metabolic changes in gnotobiotic bees that were colonized with a complete microbiota. The authors found that honey bee gut bacteria can metabolize a wide range of compounds in the gut and provide insights into how metabolic activities are divided within gut communities.

Results revealed genomic changes underlying host specialization.
