Fungal Endosymbionts of Seaweeds
2011Seaweeds are being studied for their role in supporting coastal marine life and nutrient cycling and for their bioactive metabolites. For a more complete understanding of seaweed communities, it is essential to obtain information about their interactions with various other components of their ecosystem.

In the past two decades, many Coxiella-like bacteria have been found in hard ticks and soft ticks as well as in vertebrate hosts. It is interesting to note that many ticks harbor Coxiella-like bacteria with high prevalence. Coxiella-like bacteria and virulent Coxiella burnetii have high homology to each other; they form a monophyletic clade based on ...

WOLBACHIA ENDOSYMBIONTS IN FLEAS (SIPHONAPTERA)
Journal of Parasitology, 2003Intracellular endosymbionts, Wolbachia spp., have been reported in many different orders of insects and in nematodes but not previously in fleas. This is the first conclusive report of Wolbachia spp. within members of the Siphonaptera. Using nested polymerase chain reaction (PCR) targeting of the 16S ribosomal RNA gene, we screened for Wolbachia spp ...

Identification of Pelomyxa palustris Endosymbionts
Protist, 2017Pelomyxa palustris is a giant anaerobic/microaerobic amoeba, characterized by a number of exceptional cytological and physiological features, among them the presumed absence of energy producing organelles and the presence of endosymbiotic bacteria. These endosymbionts have been previously distinguished as: a large rectangular-shaped Gram-variable rod ...

The Endosymbiont Hypothesis Revisited
1992Publisher Summary This chapter highlights endosymbiont hypothesis. All contemporary genomes (including those of plastids and mitochondria) ultimately derive from a single genome—the genome of a single, presumably cellular, entity which was the ancestor of all surviving forms of live.

Biology of Fungi and Their Bacterial Endosymbionts
Annual Review of Phytopathology, 2018Heritable symbioses, in which endosymbiotic bacteria (EB) are transmitted vertically between host generations, are an important source of evolutionary novelties. A primary example of such symbioses is the eukaryotic cell with its EB-derived organelles.

Bacterial Endosymbionts of Acanthamoeba sp.
The Journal of Parasitology, 1985Gimenez staining of presumably axenic Acanthamoeba sp., strain HN-3, showed rod-shaped cytoplasmic inclusions. Electron microscopy of thin sections of the amebae showed these to be bacilli which measured 1.3 to 3.3 microns by 0.22 to 0.33 micron. Their cell envelopes were those typical of gram-negative bacteria, surrounded by an electron-translucent ...

Diatoms, or their plastids, are symbionts of four different families of foraminifera. Evidence suggests that the evolution of these families was driven by their symbiotic relationships. All hosts are many times larger than their ancestors, have complex subcompartmentalization, and have multiple nuclei and internal organelles (e.g., Golgi, mitochondria).
