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 .
Stentor coeruleus, used in molecular biology (its genome has been sequenced), [5] and is studied as a model of single-cell regeneration.; Dictyostelium discoideum, used in molecular biology and genetics (its genome has been sequenced), and is studied as an example of cell communication, differentiation, and programmed cell death.
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 ...

When injected into plants, these proteins can enter the nucleus of the plant cell, bind plant promoter sequences, and activate transcription of plant genes that aid in bacterial infection. [7] Plants have developed a defense mechanism against type III effectors that includes R (resistance) genes triggered by these effectors. Some of these R ...
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 ...
In cell division, two identical clone daughter cells are produced. Some bacteria, while still reproducing asexually, form more complex reproductive structures that help disperse the newly formed daughter cells. Examples include fruiting body formation by myxobacteria and aerial hyphae formation by Streptomyces species, or budding. Budding ...
In bacteria, essential genes appear to be more conserved than nonessential genes [73] but the correlation is not very strong. For instance, only 34% of the B. subtilis essential genes have reliable orthologs in all Bacillota and 61% of the E. coli essential genes have reliable orthologs in all Gamma-proteobacteria . [ 72 ]
