The Syntrophy hypothesis for the origin of eukaryotes revisited [PDF]

Nature Microbiology, 2020
The discovery of Asgard archaea, phylogenetically closer to eukaryotes than other archaea, together with improved knowledge of microbial ecology, impose new constraints on emerging models for the origin of the eukaryotic cell (eukaryogenesis). Long-held views are metamorphosing in favour of symbiogenetic models based on metabolic interactions between ...

Eukaryogenesis, a syntrophy affair [PDF]

Nature Microbiology, 2019
Eukaryotes evolved from a symbiosis involving Alphaproteobacteria and archaea phylogenetically nested within the Asgard clade. Two recent studies explore the metabolic capabilities of Asgard lineages, supporting refined symbiotic metabolic interactions that might have operated at the dawn of eukaryogenesis.

Tracing the evolutionary pathway: on the origin of mitochondria and eukaryogenesis. [PDF]

FEBS J
This study examines the stepwise transition from archaeal–bacterial associations to the emergence of eukaryotic cells. Metabolic cooperation and endosymbiosis fostered ecological and genetic integration, with extensive gene transfer reshaping host biology.

Genesis of ectosymbiotic features based on commensalistic syntrophy. [PDF]

Sci Rep
Abstract The symbiogenetic origin of eukaryotes with mitochondria is considered a major evolutionary transition. The initial interactions and conditions of symbiosis, along with the phylogenetic affinity of the host, are widely debated.

“Candidatus Ethanoperedens,” a Thermophilic Genus of Archaea Mediating the Anaerobic Oxidation of Ethane

mBio, 2020
Cold seeps and hydrothermal vents deliver large amounts of methane and other gaseous alkanes into marine surface sediments. Consortia of archaea and partner bacteria thrive on the oxidation of these alkanes and its coupling to sulfate reduction.

The Evolution of Microbial Facilitation: Sociogenesis, Symbiogenesis, and Transition in Individuality

Frontiers in Ecology and Evolution, 2022
Metabolic cooperation is widespread, and it seems to be a ubiquitous and easily evolvable interaction in the microbial domain. Mutual metabolic cooperation, like syntrophy, is thought to have a crucial role in stabilizing interactions and communities ...

Complete genome sequence of Syntrophobacter fumaroxidans strain (MPOB(T)). [PDF]

, 2012
Syntrophobacter fumaroxidans strain MPOB(T) is the best-studied species of the genus Syntrophobacter. The species is of interest because of its anaerobic syntrophic lifestyle, its involvement in the conversion of propionate to acetate, H2 and CO2 during ...

Microbial interspecies interactions: recent findings in syntrophic consortia

Frontiers in Microbiology, 2015
Microbes are ubiquitous in our biosphere, and inevitably live in communities. They excrete a variety of metabolites and support the growth of other microbes in a community.

Simultaneous Genome Sequencing of Prosthecochloris ethylica and Desulfuromonas acetoxidans within a Syntrophic Mixture Reveals Unique Pili and Protein Interactions

Microorganisms, 2020
Strains of Chloropseudomonas ethylica, 2-K, N2, and N3 are known to be composed of a syntrophic mixture of a green sulfur bacterium and a sulfur-reducing colorless component.

Functional responses of methanogenic archaea to syntrophic growth. [PDF]

, 2012
Methanococcus maripaludis grown syntrophically with Desulfovibrio vulgaris was compared with M. maripaludis monocultures grown under hydrogen limitation using transcriptional, proteomic and metabolite analyses.
