Enterobacteria phage λ (lambda phage, coliphage λ) is a bacterial virus, or bacteriophage, that infects the bacterial species Escherichia coli. This virus is temperate and may reside within the genome of its host through lysogeny. Lambda phage consists of a virus particle including a head (also known as a capsid), tail and tail fibers Bacteriophage lambda, a bacterial virus that infects E. coli, has been widely used as a cloning vector.As described in Ch. 21, lambda is a well-characterized virus with both lytic and lysogenic alternatives to its life cycle.Although lambda DNA circularizes for replication and insertion into the E. coli chromosome, the DNA inside the phage particle is linear (Fig. 7.11) The Bacteriophage lambda by Hershey, A.

They are still a paradigm for many areas of biology, especially gene expression (See Bacteriophage Lambda). Environmental: Bacteriophages, like bacteria, are very common in all natural environments and are directly related to the numbers of bacteria present. They are thus very common in soil and have shaped the evolution of bacteria In contrast, other dsDNA phages like T7 and lambda DNAs (which also form concatamers during replication) are always cleaved at a particular sequence in the genome, so that all the capsid-packaged linear dsDNA molecules are the same (see Fig 19.7). A different example of a dsDNA virus is Lambda (()

Enterobacteria phage λ (lambda phage, coliphage λ, officially Escherichia virus Lambda) is a bacterial virus, or bacteriophage, that infects the bacterial species Escherichia coli (E. coli).It was discovered by Esther Lederberg in 1950. The wild type of this virus has a temperate life cycle that allows it to either reside within the genome of its host through lysogeny or enter into a lytic. The lysis-lysogeny decision of bacteriophage lambda (λ) is a paradigm for developmental genetic networks. There are three key features, which characterize the network. First, after infection of the host bacterium, a decision between lytic or lysogenic development is made that is dependent upon environmental signals and the number of infecting phages per cell. Second, the lysogenic prophage. Abstract: The bacterial virus lambda ( ) is a temperate bacteriophage that can lysogenize host Escherichia coli (E. coli) cells.

Authors M R Geier, M E Trigg, C R Merril. PMID: 4586796. Genetic organization of lambda DNA. The lambda phage is a typical example of bacteriophage which has a polyhedral head and tail. The DNA is protected by the polyhedral structure, and the tail interacts with the specific site of bacteria for attachment. Lambda phage usually infects E. coli. The DNA of lambda phage is 49 kb of size New species arise through the evolution of barriers to reproduction. This process is well understood where the emerging species are spatially isolated from one another. But the process of sympatric speciation—where the diverging species co-occur—is more enigmatic. Bacterial viruses make good models for addressing such questions because of their rapid generation times

Nucleotide Sequences 1986/1987, Volume V: Bacteria and Bacteriophage presents data that reflect the information found in GenBank Release 44.0 of August 1986. This book provides information pertinent to the unique international collaboration between two leading nucleotide sequence data libraries, one based in Europe and one in the United States Cellular decision-making guides complex development such as cell differentiation and disease progression. Much of our knowledge about decision-making is derived from simple models, such as bacteriophage lambda infection, in which lambda chooses between the vegetative lytic fate and the dormant lysogenic fate. This paradigmatic system is broadly understood but lacking mechanistic details.
