Symbiont-mediated cytoplasmic incompatibility: What have we learned in 50 years?
eLife, 2020 Cytoplasmic incompatibility (CI) is the most common symbiont-induced reproductive manipulation. Specifically, symbiont-induced sperm modifications cause catastrophic mitotic defects in the fertilized embryo and ensuing lethality in crosses between ...

Biological invasions and endosymbiosis in Arthropods, a case study:Bemisia tabaci : S1403TH01 Invasive Species and Quarantine [PDF]
, 2012 Biological invasions are more and more frequent worldwide and understanding this process is a big issue. Invasive success depends on several traits permitting local adaptation.

Difficult phylogenetic questions: more data, maybe; better methods, certainly
BMC Biology, 2011 Contradicting the prejudice that endosymbiosis is a rare phenomenon, Husník and co-workers show in BMC Biology that bacterial endosymbiosis has occured several times independently during insect evolution.

Challenging Eukaryogenesis: The Story of the Eukaryotic Ancestor [PDF]
arXiv, 2020 As the question of the origins of eukaryotes comes closer to an answer, the interactions between the archaeal ancestor to eukaryotes and environmental, molecular, bacterial, other influences and symbionts have become increasingly relevant. Various studies have pointed towards the Lokiarchaeota as a close archaeal relative to the eukarya.

Protein import into the endosymbiotic organelles of apicomplexan parasites [PDF]
, 2018 The organelles of endosymbiotic origin, plastids, and mitochondria, evolved through the serial acquisition of endosymbionts by a host cell. These events were accompanied by gene transfer from the symbionts to the host, resulting in most of the organellar

Frontiers in Marine Science, 2020 Kleptoplasty or acquisition of chloroplasts from ingested photosynthetic organisms, is thought to be a key factor in determining the trophic requirements and carbon mineralization of foraminifera, consequently influencing their ecology, evolution, and ...

Evolution and ontogeny of bacteriocytes in insects
Frontiers in Physiology, 2022 The ontogenetic origins of the bacteriocytes, which are cells that harbour bacterial intracellular endosymbionts in multicellular animals, are unknown. During embryonic development, a series of morphological and transcriptional changes determine the fate

iScience, 2023 Summary: Endosymbiosis with chemosynthetic Gammaproteobacteria is widely recognized as an adaptive mechanism of siboglinid tubeworms, yet evolution of these endosymbionts and their driving forces remain elusive.

Genetic basis for the establishment of endosymbiosis in Paramecium
The ISME Journal, 2019 The single-celled ciliate Paramecium bursaria is an indispensable model for investigating endosymbiosis between protists and green-algal symbionts. To elucidate the mechanism of this type of endosymbiosis, we combined PacBio and Illumina sequencing to ...

Paulinella chromatophora – rethinking the transition from endosymbiont to organelle
Acta Societatis Botanicorum Poloniae, 2014 Eukaryotes co-opted photosynthetic carbon fixation from prokaryotes by engulfing a cyanobacterium and stably integrating it as a photosynthetic organelle (plastid) in a process known as primary endosymbiosis.
