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.

Life Cycle Analysis of Endosymbiotic Algae in an Endosymbiotic Situation with Paramecium bursaria Using Capillary Flow Cytometry

open access: yesEnergies, 2017
Along with algae as producers in ecosystems and industrial applications, some microalgae existing in special ecological niches through endosymbiosis with other organisms represent fascinating examples of biological evolution.

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 ...

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.

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

Algal Diversity in Paramecium bursaria: Species Identification, Detection of Choricystis parasitica, and Assessment of the Interaction Specificity

open access: yesDiversity, 2020
The ‘green’ ciliate Paramecium bursaria lives in mutualistic symbiosis with green algae belonging to the species Chlorella variabilis or Micractinium conductrix. We analysed the diversity of algal endosymbionts and their P. bursaria hosts in nine strains

Relevance of sex-differenced analyses in bioenergetics and nutritional studies

open access: yesFrontiers in Nutrition, 2022
Sex-biased analyses still remain as one of the biggest limitations to obtain universal conclusions. In biomedicine, the majority of experimental analyses and a significant amount of patient-derived cohort studies exclusively included males.

The Basic Genetic Toolkit to Move in with your Photosynthetic Partner

open access: yesFrontiers in Ecology and Evolution, 2015
The origin of photosynthetic organelles via endosymbiosis more than 1 Gya ago was a major detonator of eukaryotic diversification. The evolution of a stable endosymbiotic relationship between eukaryotic cells and photosynthetic cyanobacteria involved ...

Surfing the vegetal pole in a small population: extracellular vertical transmission of an 'intracellular' deep-sea clam symbiont [PDF]

open access: yesRoyal Society Open Science, 2016
Symbiont transmission is a key event for understanding the processes underlying symbiotic associations and their evolution. However, our understanding of the mechanisms of symbiont transmission remains still fragmentary.

Characterisation of an Escherichia coli line that completely lacks ribonucleotide reduction yields insights into the evolution of parasitism and endosymbiosis

open access: yeseLife, 2023
Life requires ribonucleotide reduction for de novo synthesis of deoxyribonucleotides. As ribonucleotide reduction has on occasion been lost in parasites and endosymbionts, which are instead dependent on their host for deoxyribonucleotide synthesis, it ...
