tRF 903 corresponds to the cloned bacterial sequence which most closely matches Enterococcus faecalis R090 (Table 1), which was totally removed from populations fed antibiotics (Fig. 2).
The clade "Bact4ext" holds GGT sequences from bacterial organisms which are known to inhabit extreme environments.
An asterisk identifies bacterial genomes which are completely sequenced, whereas other sequences are from partially or incompletely sequenced genomes.
The development of inexpensive genome sequencing technologies and efficient assembly methods has revolutionized the study of bacterial genomes, which are being sequenced and assembled on a daily basis.
An unresolved binary constraint tree was generated in MacClade v4.08, in which bacterial sequences are monophyletic, as are nonbacterial sequences, with all other topology unconstrained.
In order for such acceleration to result in the nesting of these sequences within bacterial clades (which is what we observe) this acceleration must have been coupled with extensive convergent evolution as well.
Concordance of the Vidania phylogeny with the phylogeny of the planthopper hosts (reconstructed based on sequence data from five genes generated from the same insect specimens from which the bacterial sequences were obtained) was supported by statistical tests of codiversification.
Subsequently, numerous bacterial genomes have been sequenced, many of which are closed solely with PacBio data [ 19].
With the advent of molecular techniques, especially the development of next-generation high-throughput sequencing techniques, more and more bacterial phylotypes, which were undiscovered by traditional microbiological techniques, were found in these habitats of the human body.
