endosymbiont (given by a number of authors) is just not borne out by our knowledge of the structure and function of the nucleus,» concludes Anthony Poole of Massey University

Gil is now sequencing and comparing the genomes of bacteria that live within insects
in a mutually beneficial relationship, the so - called

One obvious difference, however, is that organelles are found
in almost every cell
in an organism, while
endosymbionts, because their main role is to provide nutrients for their hosts, are found only
in certain cells.

endosymbionts, such as Tremblaya, are fairly common
in invertebrates, but are rare
in humans and other vertebrates.)
When Cary applied for the program at Scripps, his background with bivalves caught the attention of Horst Felbeck, one of the first to identify
endosymbionts (symbiotic microbes that reside within the host cell)
in vent clams and mussels.

endosymbionts of marine animals and protozoa, and play an important part

endosymbionts become dependent on their organelles and are unable to survive
in their absence.
c) The eukaryote then began a mutually beneficial (symbiotic) relationship with it whereby the eukaryote provided protection and nutrients to the prokaryote, and

in the absence of viral infection, demonstrating that harbouring this protective
endosymbiont is associated with a fitness cost.
