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.

The microbiome extends host evolutionary potential

Nature Communications, Год журнала: 2021, Номер 12(1)

Опубликована: Авг. 26, 2021

Abstract The microbiome shapes many host traits, yet the biology of microbiomes challenges traditional evolutionary models. Here, we illustrate how integrating into quantitative genetics can help untangle complexities host-microbiome evolution. We describe two general ways in which may affect potential: by shifting mean phenotype and changing variance population. synthesize literature across diverse taxa discuss these scenarios could shape response to selection. conclude outlining key avenues research improve our understanding complex interplay between hosts microbiomes.

Spatial self-organization favors heterotypic cooperation over cheating

Heterotypic cooperation—two populations exchanging distinct benefits that are costly to produce—is widespread. Cheaters, exploiting while evading contribution, can undermine cooperation. Two mechanisms stabilize heterotypic In ‘partner choice’, cooperators recognize and choose cooperating over cheating partners; in fidelity feedback’, fitness-feedback from repeated interactions ensures aiding your partner helps yourself. How might a spatial environment, which facilitates interactions, promote fitness-feedback? We examined this process through mathematical models engineered Saccharomyces cerevisiae strains incapable of recognition. Here, their cooperative partners (partners) exchanged essential metabolites. Cheaters exploited partner-produced metabolites without reciprocating, were competitively superior cooperators. Despite initially random distributions, gained more neighbors than cheaters did. The less cheater contributed, the it was excluded disfavored. This self-organization, driven by asymmetric fitness effects on during cell growth into open space, achieves assortment.
