This list of sequenced eubacterial genomes contains most of the eubacteria known to have publicly available complete genome sequences.Most of these sequences have been placed in the International Nucleotide Sequence Database Collaboration, a public database which can be searched [1] on the web.

Bacterial conjugation is the transfer of genetic material (plasmid) between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. [1] Discovered in 1946 by Joshua Lederberg and Edward Tatum, [ 2 ] conjugation is a mechanism of horizontal gene transfer as are transformation and transduction although ...
Bacterial genomes can range in size anywhere from about 130 kbp [1] [2] to over 14 Mbp. [3] A study that included, but was not limited to, 478 bacterial genomes, concluded that as genome size increases, the number of genes increases at a disproportionately slower rate in eukaryotes than in non-eukaryotes.
Gene transfer systems that have been extensively studied in bacteria include genetic transformation, conjugation and transduction. Natural transformation is a bacterial adaptation for DNA transfer between two cells through the intervening medium. The uptake of donor DNA and its recombinational incorporation into the recipient chromosome depends ...
Vibrio – a genus of comma shaped bacteria first described in 1854 [12]) Bacterium – a genus of rod shaped bacteria first described in 1828, that later gave its name to the members of the Monera, formerly referred to as "a moneron" (plural "monera") in English and "eine Moneren "(fem. pl. "Moneres") in German
The bacteria that naturally colonise certain crops have also been modified, in some cases to express the Bt genes responsible for pest resistance. Pseudomonas strains of bacteria cause frost damage by nucleating water into ice crystals around themselves. This led to the development of ice-minus bacteria, that have the ice-forming genes removed ...
An example is the viral transfer of DNA from one bacterium to another and hence an example of horizontal gene transfer. [2] [3] [page needed] Transduction does not require physical contact between the cell donating the DNA and the cell receiving the DNA (which occurs in conjugation), and it is DNase resistant (transformation is susceptible to ...
