Applying the core microbiome to understand host–microbe systems

Abstract The host‐associated core microbiome was originally coined to refer common groups of microbes or genes that were likely be particularly important for host biological function. However, the term has evolved encompass variable definitions across studies, often identifying key with respect their spatial distribution, temporal stability ecological influence, as well contribution function and fitness. A major barrier reaching a consensus over how define its relevance biological, evolutionary theory is lack precise terminology associated definitions, persistent association Common, microbiomes can together generate insights into processes act independently function, while functional host‐adapted cores distinguish between facultative near‐obligate symbionts differ in effects on This commentary summarizes five broad have been applied literature, highlighting strengths limitations advancing our understanding host–microbe systems, noting where they are overlap, discussing potential No one definition capture range population.

Microbial evolution and transitions along the parasite–mutualist continuum

Nature Reviews Microbiology, Journal Year: 2021, Volume and Issue: 19(10), P. 623 - 638

Published: April 19, 2021

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.

Ecology and Evolution of Insect–Fungus Mutualisms

Annual Review of Entomology, Journal Year: 2019, Volume and Issue: 65(1), P. 431 - 455

Published: Oct. 14, 2019

The evolution of a mutualism requires reciprocal interactions whereby one species provides service that the other cannot perform or performs less efficiently. Services exchanged in insect–fungus mutualisms include nutrition, protection, and dispersal. In ectosymbioses, which are focus this review, fungi can be consumed by insects degrade plant polymers defensive compounds, thereby making substrate available to insects. They also protect against environmental factors produce compounds antagonistic microbial competitors. Insects disperse provide fungal growth substrates protection. Insect–fungus transition from facultative obligate, each partner is no longer viable on its own. Obligate dependency has ( a) resulted morphological adaptations fungi, b) driven social behaviors some groups insects, c) led loss sexuality mutualists.

Insects share an intimate relationship with their gut microflora and this symbiotic association has developed into essential evolutionary outcome intended for survival through extreme environmental conditions.

Symbioses shape feeding niches and diversification across insects

Nature Ecology & Evolution, Journal Year: 2023, Volume and Issue: 7(7), P. 1022 - 1044

Published: May 18, 2023

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.

Millions of years co-evolution between animals and their associated microbial communities have shaped diversified the nature relationship. Studies continue to reveal new layers complexity in host–microbe interactions, fate which depends on a variety different factors, ranging from neutral processes environmental factors local dynamics. Research is increasingly integrating ecosystem-based approaches, metagenomics mathematical modelling disentangle individual contribution ecological microbiome evolution. Within this framework, host are known be among dominant drivers composition animal species. However, extent they shape assembly evolution remains unclear. In review, we summarize our understanding how drive these dynamics conserved vary across taxa. We conclude by outlining key avenues for research highlight need implementation modifications existing theory fully capture host-associated microbiomes.
