Transduction is the term used to designate bacteriophage-mediated transfer of DNA from one cell (a donor) to another cell (a recipient). It was first described by Norton Zinder and Joshua Lederberg for Salmonella and phage P22, but has since been shown to occur in many other bacteria and to involve a variety of bacteriophages. Depending on which virus is involved, the donor cell DNA may or may not be associated with viral DNA inside the capsid of the bacteriophage. However, in all cases of transduction it is necessary for donor cells to lyse and for virions carrying host DNA (the transducing particles) to be capable of infecting new host cells. A cell that has acquired a recombinant phenotype by this process is called a transductant.
