Conjugation is how a bacterium can share the information on a plasmid with its neighbors. SCIENCE VIDEOS but those that do can share these advantageous molecules with other bacteria in a process called conjugation. Conjugation is one the three mechanism of DNA exchange between bacteria, the other being transformation and transduction. Conjugation occurs between two living cells, involves cell to cell contact, and requires mobilization of either a plasmid or a chromosome of donor bacterial cells. Bacterial conjugation and transfer of F plasmid. Plasmids 101: Transformation, Transduction, Bacterial Conjugation, and Transfection. Horizontal gene transfer (HGT) is the movement of genetic material between organisms. It plays a key role in bacterial evolution and is the primary mechanism by which bacteria have gained antibiotic resistance and virulence. Conjugation in bacteria is a process in which plasmids are transferred by themselves alone or along with other DNA element from one cell to another cell through conjugation tube. Conjugation occur by physical contact between cells. The cell which transfer plasmid is called donor and the cell which receive the plasmid is called recipient. Plasmid Transfer. Once the cytoplasm of the donor and recipient cell are physically linked, Conjugation in bacteria was discovered by a) Beadles and Tatum. b) Zinder and Lederberg. c) Gonococci with plasmid-mediated high-level resistance to tetracycline, with minimal inhibitory concentrations (MICs) of 16 mg/L or greater, carry the 24.5-mDa conjugative plasmid into which the tetM transposon has been inserted. 29 The tetM determinant also confers tetracycline resistance to a variety of other bacteria, including some Streptococcus and Mycoplasma spp. and various genital However, multicellular Gram-positive bacteria belonging to the streptomycetes appear to have evolved another mechanism for conjugative plasmid spread reminiscent of the machinery involved in bacterial cell division and sporulation, which transports double-stranded DNA from donor to recipient cells. Bacterial Conjugation. Bacterial conjugation is one of the principal means of dissemination of genetic information among microbes and from bacteria to other domains of life including plants and other eukaryotes. From: Encyclopedia of Microbiology (Third Edition), 2009. Related terms: Plasmid; Nested Gene; Bacterium; Conjugation; Mutation; Bacteriophage Mechanism of Bacterial Conjugation. The mechanism of conjugation includes the following steps: Mating pair formation: A donor cell which having self-transmissible plasmid will form a pilus that helps in attachment with the recipient bacterial cell.; Signalling by coupling protein: Coupling protein complex is a component of Mpf or mating pair formation complex. Bacterial Conjugation Definition. Conjugation is the transfer of a plasmid or other self-transmissible DNA element and sometimes chromosomal DNA from a donor cell to a recipient cell via direct contact usually mediated by a conjugation pilus or sex pilus. Recipients of the DNA transferred by conjugation are called transconjugants.
