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. Bacterial conjugation and transfer of F plasmid. 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. 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: steps and mechanism of transfer of plasmid from donor to recipient cell 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. 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 Bacterial conjugation is a way by which a bacterial cell transfers genetic material to another bacterial cell. The genetic material that is transferred through bacterial conjugation is a small plasmid, known as F-plasmid (F for fertility factor), that carries genetic information different from that which is already present in the chromosomes of the bacterial cell. Bacterial conjugation Conjugation was the first extensively studied method of gene transfer and was discovered in 1946 by Joshua Lederberg and Edward Tatum when they observed genetic recombination between two nutritional deficient E. coli strains that resulted in a wild type E. coli ( Griffiths et al., 2000 ).
