Conjugative transfer is a primary means of spread of mobile genetic elements (plasmids and
transposons) between bacteria. It leads to the dissemination and evolution of the genes …

Major impetus for these fundamental studies of bacterial genetics has come from the quest
to understand ways by which bacteria acquire resistance to the onslaught of antibiotics used …

Conjugative transposons are transposable elements that can cause gram-positive bacteria
to be conjugational donors to promote antibiotic resistance. The can conjugate by moving …

Publisher Summary The specification of a conjugation system requires a relatively large
amount of DNA and typically takes up about one-third of the plasmid genome. In case of the …

Quantitative measurements of horizontal DNA transfer are critical if one wishes to address
questions relating to ecology, evolution and the safe use of recombinant bacteria …

Plasmids isolated from Gram-negative bacteria can be divided into two major groups: large
plasmids (> 30 kb) that determine conjugation systems, and small plasmids (< 10 kb) that do …

Bacterial conjugation is one of the fundamental processes for gene dissemination or
horizontal gene transfer in nature and involves the transfer of DNA between bacteria in close …

Publisher Summary Conjugation is the process whereby DNA is transferred from one
bacterial cell to another by a mechanism that requires cell-to-cell contact. Requirement for …

Bacterial plasmids originating in a wide range of genera are being studied from a variety of
perspectives in hundreds of laboratories around the globe. These elements are well known …
