Many animals are dependent on microbial partners that provide essential nutrients lacking from their diet. Ticks, whose diet consists exclusively vertebrate blood, rely maternally inherited bacterial symbionts to supply B vitamins. While previously studied tick species consistently harbor a single lineage of those nutritional symbionts, we evidence here the invasive Hyalomma marginatum harbors unique dual-partner system between an ancestral symbiont, Francisella , and more recently acquired Midichloria . Using metagenomics, show exhibits extensive genome erosion endangers symbiotic interactions. Its includes folate riboflavin biosynthesis pathways but deprived functional biotin account massive pseudogenization. Co-symbiosis compensates this deficiency since encompasses intact operon, which was primarily via lateral gene transfer unrelated intracellular bacteria commonly infecting arthropods. Thus, in H. mosaic co-evolved incorporating combinations distant phylogenetic origins emerged prevent collapse symbiosis. Such dual endosymbiosis never reported other blood feeders documented agricultural pests feeding plant sap, suggesting it may be key mechanism for advanced adaptation arthropods specialized diets.

Virtually all plants and animals, including humans, are home to symbiotic microorganisms. Symbiotic interactions can be neutral, harmful or have beneficial effects on the host organism. However, growing evidence suggests that microbial symbionts evolve rapidly, resulting in drastic transitions along parasite–mutualist continuum. In this Review, we integrate theoretical empirical findings discuss mechanisms underpinning these evolutionary shifts, as well ecological drivers why some host–microorganism may stuck at end of addition having biomedical consequences, understanding dynamic life microorganisms reveals how symbioses shape an organism's biology entire community, particularly a changing world. for organisms. Drew, Stevens King continuum, underlying changes, selective pressures involved common approaches studying them.

For over 300 million years, insects have relied on symbiotic microbes for nutrition and defence. However, it is unclear whether specific ecological conditions repeatedly favoured the evolution of symbioses, how this has influenced insect diversification. Here, using data 1,850 microbe-insect symbioses across 402 families, we found that symbionts allowed to specialize a range nutrient-imbalanced diets, including phloem, blood wood. Across only limiting nutrient consistently associated with obligate symbiosis was B vitamins. The shift new facilitated by symbionts, had mixed consequences In some cases, such as herbivory, resulted in spectacular species proliferation. other niches, strict feeding, diversification been severely constrained. Symbioses therefore appear solve widespread deficiencies insects, but depend feeding niche invaded.

While the importance of mutualisms across tree life is recognized, it not understood why some organisms evolve high levels dependence on mutualistic partnerships, while other species remain autonomous or retain regain minimal partners. We identify four main pathways leading to evolution dependence. Then, we evaluate current evidence for three predictions: ( a) Mutualisms with different have distinct stabilizing mechanisms against exploitation and cheating, b) less dependent mutualists will return autonomy more often than those that are highly dependent, c) obligate should be context facultative ones. Although find supporting all predictions, stress partners follow diverse paths toward—and away from—dependence. also highlight need better examine asymmetry in partner Recognizing how variation influences stability, breakdown, generates new hypotheses regarding benefits partnerships differ over time space.

The outer membrane (OM) of Gram-negative bacteria poses a barrier to antibiotic entry due its high impermeability. Thus, there is an urgent need study the function and biogenesis OM. In Enterobacterales , order with many pathogenic members, one components OM enterobacterial common antigen (ECA). We have known presence ECA on cell surface for years, but properties only more recently begun be unraveled.

Abstract Microorganisms often live in symbiosis with their hosts, and some are considered mutualists, where all species involved benefit from the interaction. How free-living microorganisms have evolved to become mutualists is unclear. Here we report an experimental system which non-symbiotic Escherichia coli evolves into insect mutualist. The stinkbug Plautia stali typically associated its essential gut symbiont, Pantoea sp., colonizes a specialized symbiotic organ. When sterilized newborn nymphs were infected E. rather than only few insects survived, exhibited specific localization organ vertical transmission offspring. Through transgenerational maintenance P. , several hypermutating lines independently support host’s high adult emergence improved body colour; these called ‘mutualistic’ . These mutants slower bacterial growth, smaller size, loss of flagellar motility lack extracellular matrix. Transcriptomic genomic analyses revealed independent mutations that disrupted carbon catabolite repression global transcriptional regulator system. Each mutation reproduced mutualistic phenotypes when introduced wild-type confirming single can make findings provide for future work on host–microbe symbioses may explain why microbial mutualisms omnipresent nature.

Abstract Chlamydiae is a bacterial phylum composed of obligate animal and protist endosymbionts. However, other members the Planctomycetes–Verrucomicrobia–Chlamydiae superphylum are primarily free living. How transitioned to an endosymbiotic lifestyle still largely unresolved. Here we reconstructed species relationships modelled genome evolution. Gene content reconstruction from 11,996 gene families suggests motile facultatively anaerobic last common ancestor that had already gained characteristic endosymbiont genes. Counter expectations for streamlining in strict endosymbionts, detected substantial gain within Chlamydiae. We found divergence energy metabolism aerobiosis observed extant lineages emerged later during chlamydial In particular, metabolic aerobic genes more metabolically versatile protist-infecting chlamydiae were gained, such as respiratory chain complexes. Our results show complexity can increase evolution, adding additional perspective understanding symbiont evolutionary trajectories across tree life.
