- n. a large group of bacteria having rigid cell walls; motile types have flagella
Sorry, no etymologies found.
In fact, it looks as if the homologous sequences of key proteins of the flagellar motor is a continuum of different eubacteria show sequence similarity.
In a highly regarded publication have Liu & Ochman (2007b) proposed a core set of 24 proteins, which occurs in all previously genomsequenzierten eubacteria (see above).
Because the molecular motor proteins, and the pedigrees of the parties agree to some bacterial species, and because the motor genes are widespread on the eubacteria, Liu & Ochman conclude that the core proteins were created of the motor before the diversification of the eubacteria.
This was for various eubacteria such as Escherichia Giron et al.
Until recently known simply as 'bacteria', the 2 main groups recognized today are archaeabacteria and eubacteria which differ in the composition of their cell membranes.
Good point though – those resources don't spend much time on the cellular and molecular evidence linking not just phyla but kingdoms in the tree of life, and I don't have a handy reference for that, but generally the evidences surround the cellular and molecular homologies between animals, plants, fungi, protists, eubacteria and archea.
¦ It was all DNA and genes and chromosomes and microbiology and eubacteria these days.
The protein composition of the mitoribosome has been estimated to be about 75%, which indicates that large parts of bacterial rRNA domains have been replaced by protein components during mitochondrial evolution from a eubacteria-like endosymbiont in eukaryotic cell progenitors.
I know much less about viruses than they know about me, but this Carl Zimmer article indicates that the currently popular theories of viral evolution have viruses emerging before there were animals or plants; possibly even before eukaryotes, eubacteria and archaea diverged.
The biggest break in life, she explained, was between the prokaryotes (cells with nucleoids: monera, prokaryota; archaebacteria, eubacteria) and eukaryotes (cells with nuclei: protoctista, fungi, plantae, animalia).
