Endosymbiosis: The feeling is not mutual [PDF]
Endosymbiosis is an idea that provided a remarkable amount of explanatory power about the origins of eukaryotic organelles. But it also promoted a number of assumptions that have also been influential, but are less well-examined. Here we look at two of these to see whether or not they fit current evidence.

What Does It Take to Evolve A Nitrogen-Fixing Endosymbiosis?
Plant rhizo- and phyllospheres are exposed to a plethora of nitrogen-fixing bacteria, providing opportunities for the establishment of symbiotic associations.

Applying endosymbiosis theory: Tourism and its young workers [PDF]
Building on systems theory and its applications in tourism management, we introduce the natural science evolutionary 'endosymbiosis theory' to interpret the inter-dependencies of youth employment and tourism.

Endosymbiosis in Blastocystis hominis
Experimental Parasitology, 1976Abstract Examination of eight strains of axenically grown Blastocystis hominis by Nomarski interference optics revealed the presence in all strains of intracellular bacterialike spheres and rods, which were named alpha. These structures were confirmed by transmission (TEM) and freeze fracture (FEM) electron microscopy.

The science behind evolution suggests that the transition from cells without a nucleus to cells with a nucleus is perhaps the single greatest leap between there and here, and that it came about by the inclusion of some cells in some other cells. The term of art here, endosymbiosis, credits the ability to respire, move, and photosynthesize as results of

Endosymbiosis, cell evolution, and speciation
Theory in Biosciences, 2005In 1905, the Russian biologist C. Mereschkowsky postulated that plastids (e.g., chloroplasts) are the evolutionary descendants of endosymbiotic cyanobacteria-like organisms. In 1927, I. Wallin explicitly postulated that mitochondria likewise evolved from once free-living bacteria.

Parasitoids, polydnaviruses and endosymbiosis
Parasitology Today, 1990Symbiotic associations traditionally have been treated as evolutionary curios rather than as a major source of evolutionary innovation. Recent research on a wide variety of organisms is changing this view and is breaking down the barriers between the traditional categories of parasitism, commensalism and mutualism, to produce a more flexible view of ...

Bacterial endosymbiosis in amoebae
Trends in Cell Biology, 1995The large, free-living amoebae are inherently phagocytic. They capture, ingest and digest microbes within their phagolysosomes, including those that survive in other cells. One exception is an unidentified strain of Gram-negative, rod-shaped bacteria that spontaneously infected the D strain of Amoeba proteus and came to survive inside them.

Endosymbiosis and its significance in dermatology
Journal of the European Academy of Dermatology and Venereology, 2017AbstractProposed at the beginning of the twentieth century to explain the origin of eukaryotic organelles from prokaryotes, endosymbiosis is now medically defined by various interaction patterns between microorganisms and their residing hosts, best exemplified by the bacterial endosymbiont Wolbachia identified in arthropods and filarial nematodes ...
