Connecting and integrating cooperation within and between species

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 379(1909)

Published: July 22, 2024

There has long been a fundamental divide in the study of cooperation: researchers focus either on cooperation within species, including but not limited to sociality, or else between commonly termed mutualism. Here, we explore ecologically and evolutionarily significant ways which within- between-species interact. We highlight two primary cross-linkages. First, one type can change context other functions, thus potentially its outcome. delineate three possibilities: (i) within-species modulates benefits for heterospecific partner; (ii) affects dynamics cooperation; (iii) both processes take place interactively. The second cross-linkage emerges when resources services that makes available are obtainable from members same species different species. This brings at levels into direct interaction, some extent obscuring distinction them. expand these intersections diversity taxa interaction types.

Impact of horizontal gene transfer on emergence and stability of cooperative virulence in Salmonella Typhimurium

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: April 11, 2022

Abstract Intestinal inflammation fuels the transmission of Salmonella Typhimurium ( S .Tm). However, a substantial fitness cost is associated with virulence expression. Mutations inactivating transcriptional regulators generate attenuated variants profiting from without enduring cost. Such interfere fully virulent clones. Horizontal transfer functional regulatory genes (HGT) into could nevertheless favor evolution. To address this hypothesis, we cloned hilD , coding for master regulator virulence, conjugative plasmid that highly transferrable during intestinal colonization. The resulting mobile allele allows to emerge avirulent populations, and be restored in mutants competing against clones within-host. mutations quickly arise. stability mediated by HGT strongly limited its cost, which depends on expression level, timing transmission. We conclude robust evolution costly requires additional selective forces such as narrow population bottlenecks

Eco-evolutionary modelling of microbial syntrophy indicates the robustness of cross-feeding over cross-facilitation

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Jan. 17, 2023

Syntrophic cooperation among prokaryotes is ubiquitous and diverse. It relies on unilateral or mutual aid that may be both catalytic metabolic in nature. Hypotheses of eukaryotic origins claim mitochondrial endosymbiosis emerged from mutually beneficial syntrophy archaeal bacterial partners. However, there are no other examples prokaryotic leading to endosymbiosis. One potential reason when externalized products become public goods, they incite social conflict due selfish mutants undermine any mutualistic interactions. To rigorously evaluate these arguments, here we construct a general mathematical framework the ecology evolution different types syntrophic partnerships. We do so microbial eukaryogenetic context. Studying case where partners cross-feed each other's self-inhibiting waste, show cooperative partnerships will eventually dominate over mutants. By contrast, systems producers actively secrete enzymes cross-facilitate their partners' resource consumption not robust against cheaters evolutionary time. conclude cross-facilitation unlikely provide an adequate origin for endosymbiosis, but cross-feeding mutualisms indeed have played role.

Study of tree shrew biology and models: A booming and prosperous field for biomedical research

动物学研究, Journal Year: 2024, Volume and Issue: 45(4), P. 877 - 909

Published: Jan. 1, 2024

The tree shrew (Tupaia belangeri) has long been proposed as a suitable alternative to non-human primates (NHPs) in biomedical and laboratory research due its close evolutionary relationship with primates. In recent years, significant advances have facilitated studies, including the determination of genome, genetic manipulation using spermatogonial stem cells, viral vector-mediated gene delivery, mapping brain atlas. However, limited availability shrews globally remains substantial challenge field. Additionally, determining key questions best answered constitutes another difficulty. Tree models historically used study hepatitis B virus (HBV) C (HCV) infection, myopia, psychosocial stress-induced depression, more studies focusing on developing animal for infectious neurodegenerative diseases. Despite these efforts, impact not yet matched that rodent or NHP research. This review summarizes prominent advancements reflects biological addressed this model.

Biofilm formation is an important and ubiquitous mode of growth among bacteria. Central to the evolutionary advantage biofilm cell-cell cell-surface adhesion achieved by a variety factors, some which are diffusible compounds that may operate as classical public goods-factors costly produce but benefit other cells. An outstanding question how matrix production, in general, can be stable over timescales. In this work, using Vibrio cholerae model, we show shared proteins indeed susceptible cheater exploitation stability producing these components fundamentally depends on spatial structure, intrinsic sharing mechanisms components, flow conditions environment.

Asymmetric Metabolic Adaptations Undermine Stability in Microbial Syntrophy

ISME Communications, Journal Year: 2025, Volume and Issue: 5(1)

Published: Jan. 1, 2025

Abstract Syntrophic interaction, driven by metabolite exchange, is widespread within microbial communities. However, co-inoculation of most auxotrophic microorganisms often fails to establish a stable exchange relationship. Here, we engineered two Escherichia coli strains, each dependent on the other for essential amino acid production, investigate dynamics syntrophic relationships. Through invasion-from-rare experiments, observed rapid formation consortia stabilized frequency-dependent selection, converging 2:1 ratio lysine-to-arginine auxotrophs. laboratory evolution over 25 days revealed that interactions were evolutionarily unstable, with cocultures collapsing as ΔL cells dominated population. Reduced fitness in was emergence “selfish” phenotype, characterized decreased arginine production and exploitation lysine produced ΔA cells. Dynamic metabolic assays utilization patterns strongly influenced strain. displayed plasticity, adjusting response availability, which enabled them outcompete In contrast, lacked similar resulting their negative selection. These findings demonstrate asymmetric responses selfish phenotypes destabilize Our work underscores importance balanced exchanges developing sustainable synthetic offers insights into evolutionary cooperation.

Organisms help each other to get resources, protection from enemies, and goods, but not as much would be best for their population. Partner choice, direct reciprocity indirect foster cooperation align individual interests with the social good. However, we still do know what ecological variables affect success interaction. I simulated evolution of partner reciprocity, production a good that partners donate other. show that, few exceptions, choice evolves whenever there is an initial dilemma, under wider range conditions than reciprocity. Direct deleterious when shared highly essential or very influential. Both compel individuals produce close socially optimal quantity does so even it reciprocators are rare. Indirect succeeds can also choose partners, in most cases contributes less alleviating dilemmas. may have allowed humans use set collectively produced goods including clothing, fire, hunting tools, housing, knowledge, point they became essential.
