Maternally inherited obligate endosymbionts codiverge with their invertebrate hosts and reflect host's evolutionary history. Whiteflies (Hemiptera: Aleyrodidae) harbor one endosymbiont, Candidatus Portiera aleyrodidarum (hereafter Portiera). was anciently acquired by whitefly has been coevolving its host ever since. Uncovering the divergence of provides a fundamental basis for inspecting coevolutionary processes between bacteria hosts. To illustrate lineages across different species, we sequenced genome from Aleyrodes shizuokensis conducted comparative analysis on basic features gene evolution bacterial genomes five genera, namely Aleurodicus, Aleyrodes, Bemisia, Pealius, Trialeurodes. The results indicated that Bemisia possessed significantly larger genomes, fewer coding sequences (CDSs), lower density. Their arrangement differed notably those other genera. phylogeny nine resembled Moreover, were classified into three distinct genetic groups based distance, Aleurodicus (Aleurodicinae), (Aleyrodinae), another Trialeurrodes (Aleyrodinae).

Understanding the factors that sculpt fish gut microbiome is challenging, especially in natural populations characterized by high environmental and host genomic complexity. However, closely related hosts are valuable models for deciphering contribution of evolutionary history to assembly, through underscoring phylosymbiosis co-phylogeny patterns. Here, we propose recent diversification several

Bacterial strains that inhabit the gastrointestinal tracts of hominids have diversified in parallel (co-diversified) with their host species. The extent to which co-diversification has been mediated by partner fidelity between and hosts or geographical distance is not clear due a lack strain-level data from clades unconfounded phylogenetic relationships distributions. Here, I tested these competing hypotheses through meta-analyses 7121 gut bacterial genomes assembled wild-living ape species subspecies sampled throughout ranges equatorial Africa. Across phylogeny, strain diversification was more strongly associated phylogeny than geography. In total, approximately 14% branch length showed significant evidence independent geography, whereas only 4% geography phylogeny. Geographically co-occurring heterospecific ( Pan Gorilla ) universally maintained distinct co-diversified strains. Strains whose included Proteobacteria known adopt free-living lifestyles (e.g. Escherichia ). These results show driven primarily lineages rather

SUMMARYGut microbes provide benefits to some animals, but their distribution and effects across diverse hosts are still poorly described. There is accumulating evidence for host specificity (i.e., a pattern where different tend associate with distinct lineages), the causes consequences of this unclear. Combining experimental tests in laboratory broad surveys wild promising approach gaining comprehensive mechanistic understanding prevalence, origin, importance. Social bees represent an ideal testbed endeavor because they phylogenetically functionally diverse, host-specific, stable, tractable gut microbiota. Furthermore, western honeybee (Apis mellifera) emerging model system studying microbiota-host interactions. In review, we summarize data on prevalence strength social bee microbiota (bumblebees, stingless bees, honeybees), as well potential proven ecological molecular mechanisms that maintain specificity. Overall, found relatively strong likely results from several processes, including filtering mediated by immune priority effects. However, more research needed multiple species confirm these findings. To help future research, hypotheses field propose comparative tests. Finally, conclude review highlighting need understand how can influence health.

Abstract Purpose of Review This review explores the application classical ecological theory to host-associated microbiomes during initial colonization, maintenance, and recovery. We discuss unique challenges applying these theories host factors consider going forward. Recent Findings studies community ecology principles continue demonstrate a role for both selective stochastic processes in shaping microbiomes. However, frameworks developed describe dynamics homeostasis do not necessarily apply diseased or highly perturbed states, where large variations can potentially lead alternate stable states. Summary Despite providing valuable insights, has some challenges. The integration host-specific factors, such as genotype immune models is crucial understanding microbiome assembly stability, which could improve our ability predict outcomes health.

Animals with close social relationships often have similar microbiomes. These socially structured microbiomes can arise through multiple mechanisms that are difficult to disentangle, including transmission between partners or via structured, shared environments. Here, we review evidence for and propose methods differentiate the give rise them. We discuss evolutionary implications of these both hosts their microbiomes, possibility selects host-specialized conclude by identifying outstanding questions related evolution. identify new underutilized approaches like longitudinal study designs, strain-sharing analysis, culture-based characterization address questions.

Laboratory mice (Mus musculus domesticus) harbor gut bacterial strains that are distinct from those of wild mice1 but whose evolutionary histories poorly understood. Understanding the divergence laboratory-mouse microbiota (LGM) wild-mouse (WGM) is critical, because LGM and WGM have been previously shown to differentially affect mouse immune-cell proliferation2,3, infection resistance4, cancer progression2, ability model drug outcomes for humans5. Here, we show laboratory retained symbiont lineages diversified in parallel (co-diversified) with rodent species > 25 million years, these ancestral symbionts experienced accelerated accumulation genetic load during past ~ 120 years captivity. Compared closely related strains, co-diversified displayed significantly faster genome-wide rates fixation nonsynonymous mutations, indicating elevated drift, a difference was absent non-co-diversified clades.
