lysogeny

 [li-soj´e-ne]
the phenomenon in which a bacterium is infected by a temperature bacteriophage, the viral DNA is integrated in the chromosome of the host cell and replicated along with the host chromosome for many generations (the lysogenic cycle), and then production of virions and lysis of host cells (the lytic cycle) begins again. The lytic cycle is initiated spontaneously about once in 10,000 cell divisions or may be induced by ultraviolet light or chemical agents.

ly·sog·e·ny

(lī-soj'ĕ-nē),
The phenomenon by which a bacterium is infected by a temperate bacteriophage with DNA that is integrated into the bacterial genome and replicates along with the bacterial DNA but remains latent or unexpressed; triggering of the lytic cycle may occur spontaneously or by certain agents and will result in the production of bacteriophage and lysis of the bacterial cell.

lysogeny

(lī-sŏj′ə-nē)
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.

The phenomenon by which a bacterium is infected by a temperate bacteriophage with DNA that is integrated into the bacterial genome and replicates along with the bacterial DNA but remains latent or unexpressed; triggering of the lytic cycle may occur spontaneously or by certain agents and will result in the production of bacteriophage and lysis of the bacterial cell.

lysogeny

a state in a living bacterium when it carries a nonvirulent TEMPERATE PHAGE. In this condition the phage DNA is repressed for lytic functions (see PROPHAGE and no progeny phages are produced. The DNA may integrate into the bacterial chromosome.

Bacteria were inoculated into 25 mL of Lysogeny broth medium and incubated at 30[degrees]C for 4 h with shaking at 180 rpm.
In this process, known as lysogeny, the only thing that remains of the phage is its DNA (known as a prophage) (Figure 7-3).
The life of phages is discussed in contributions on DNA packaging in double-stranded DNA phages, general aspects of lysogeny, gene regulatory circuitry of phage lambda, regulation of lambda gene expression by transcription termination and antitermination, and phage lysis.
To better understand the genetics of P1, it is important to identify mutations within the c1 gene that prevent this lysogeny maintenance.
Lysogeny broth (LB) medium (10g/L tryptone, 5g/L yeast extract, and 10 g/L NaCl) at 37[degrees]C with shaking (200 rpm) was used for the growth of E.
An aliquot of 100 [micro]L of each dilution was used for the DNA template preparation and plated on lysogeny agar for CFU count.
A single transformed colony of Agrobacterium tumefaciens strain EHA101 was picked from solidified Lysogeny Broth (LB) medium (10 g L[?]1 NaCl, 5 g L[?]1 yeast extract,10 g L[?]1tryptone, pH 7.2) and was cultured overnight on a rotary shaker at 280C in liquid LB medium in the presence of proper concentration of selective agents.
veronii strain isolated from the medicinal leech, was cultivated in lysogeny broth, LB, at 30 [degrees]C at 200 rpm (Sambrook and Russell, 2001); Aliquots of cells representing different phases of growth were collected and flash-frozen in liquid nitrogen.
