  • n. The fusion of the nucleic acid of a bacteriophage with that of a host bacterium so that the potential exists for the newly integrated genetic material to be transmitted to daughter cells at each subsequent cell division.

  • n. The incorporation of the nucleic acid of a bacteriophage into that of a host bacterium; sometimes transmitted to daughter cells following lysis

lyso- + -geny


  • For prokaryotes in the ocean, it has been suggested that in nutrient-rich waters (characterized by a high abundance of hosts) lytic phages dominate, whereas in nutrient-poor waters (characterized by a low abundance of hosts), lysogeny dominates.

  • Returning to Melbourne in 1927, he concentrated on bacteriophage studies, making seminal discoveries in lysogeny and bacterial genetics. 4 However, in January

    The Walter and Eliza Hall Institute

  • The studies on psittacosis brought home to Burnet the importance of latent infections in diseases of vertebrates as well as in bacteria, in which he had long before recognized the nature of lysogeny.

    The Walter and Eliza Hall Institute

  • In 1958 the remarkable analogy revealed by genetic analysis of lysogeny and that of the induced biosynthesis of ß-galactosidase led François Jacob, with Jacques Monod, to study the mechanisms responsible for the transfer of genetic information as well as the regulatory pathways which, in the bacterial cell, adjust the activity and synthesis of macromolecules.

  • However, a few heretics survived - and among them Jacques Monod, who played a decisive role in my decision to return to the problem of lysogeny.

    André Lwoff - Nobel Lecture

  • The problem of the prophage had been posed, and now the history of lysogeny began again.

    André Lwoff - Nobel Lecture

  • Their investigation quickly surpasses the specific cases of the bacteriophage and of lysogeny and merged with the fundamental problems of molecular biology.

    André Lwoff - Nobel Lecture

  • In 1949, the new school of American virologists, to which virology owes so much, condemned lysogeny.

    André Lwoff - Nobel Lecture

  • Let us return to the past and attempt to determine how our knowledge and our ideas on viruses and lysogeny, as well as our concepts of the relations between cell and virus, have evolved.

    André Lwoff - Nobel Lecture

  • The decision of the genetic circuit that controls whether a virus initially chooses lysis or lysogeny is not random.
