Endosymbiosis or Bust: Influence of Ectosymbiosis on Evolution of Obligate Endosymbiosis

open access: yesThe 2022 Conference on Artificial Life, 2022
Endosymbiosis, symbiosis in which one symbiont lives inside another, is woven throughout the history of life and the story of its evolution. From the mitochondrion residing in almost every eukaryotic cell to the gut microbiome found in every human, endosymbiosis is a cornerstone of the biological processes that sustain life on Earth.

Endosymbiosis [PDF]

open access: yesCurrent Biology, 2012
The phenomenon of endosymbiosis, or one organism living within another, has deeply impacted the evolution of life and continues to shape the ecology of countless species. Traditionally, biologists have viewed evolution as a largely bifurcating pattern, reflecting mutations and other changes in existing genetic information and the occasional speciation ...

Primary endosymbiosis: have cyanobacteria and Chlamydiae ever been roommates?

open access: yesActa Societatis Botanicorum Poloniae, 2014
Eukaryotes acquired the ability to process photosynthesis by engulfing a cyanobacterium and transforming it into a genuine organelle called the plastid. This event, named primary endosymbiosis, occurred once more than a billion years ago, and allowed the

Endosymbiosis as a source of immune innovation

open access: yesComptes Rendus. Biologies, 2018
Some years ago, Lynn Margulis proposed to envision symbiosis as a source of evolutionary innovation. Here we revisit this concept in the context of insect nutritional endosymbiosis, and discuss recent data suggesting that host–endosymbiont coevolution has led to the selection of innovative strategies towards endosymbiont maintenance and control by the ...

GroEL and the maintenance of bacterial endosymbiosis [PDF]

open access: yesTrends in Genetics, 2004
Many eukaryotic organisms have symbiotic associations with obligate intracellular bacteria. The clonal transmission of endosymbionts between host generations should lead to the irreversible fixation of slightly deleterious mutations in their non-recombinant genome by genetic drift.

Endosymbiosis and Eukaryotic Cell Evolution [PDF]

open access: yesCurrent Biology, 2015
Understanding the evolution of eukaryotic cellular complexity is one of the grand challenges of modern biology. It has now been firmly established that mitochondria and plastids, the classical membrane-bound organelles of eukaryotic cells, evolved from bacteria by endosymbiosis.

Endosymbiosis: Lessons in Conflict Resolution [PDF]

open access: yesPLoS Biology, 2004
Endosymbiotic bacteria live within a host species. There are many and diverse examples of such relationships, the study of which provides important lessons for ecology and ...

Eco-Evolutionary Perspectives on Mixoplankton

open access: yesFrontiers in Marine Science, 2021
Mixotrophy, i.e., the capability of both phototrophy and phagotrophy within a single organism, is a prominent trophic mode in aquatic ecosystems. Mixotrophic strategies can be highly advantageous when feeding or photosynthesis alone does not sustain ...

Coevolution of Metabolic Pathways in Blattodea and Their Blattabacterium Endosymbionts, and Comparisons with Other Insect-Bacteria Symbioses

open access: yesMicrobiology Spectrum, 2022
Many insects harbor bacterial endosymbionts that supply essential nutrients and enable their hosts to thrive on a nutritionally unbalanced diet. Comparisons of the genomes of endosymbionts and their insect hosts have revealed multiple cases of mutually ...

Endosymbiosis: The Evil within [PDF]

open access: yesCurrent Biology, 2007
A recent study has revealed a novel feature of the symbiosis between a bacterium and a fungal pathogen. In addition to producing a pathogenic toxin, the endosymbiont of the rice pathogen Rhizopus microsporus controls the ability of the fungus to form sporangia and spores.
