The genetics and physiology of coliphage N4
Virology, 1973Amber mutants of bacteriophage N4 were isolated and classified into 27 cistrons by complementation tests. A group of 5 cistrons are essential for the synthesis of phage DNA, whereas 22 other cistrons, when defective, permit varying degrees of N4 DNA replication.

The Calcium Requirement of Coliphage T5
The Journal of Immunology, 1949Abstract Stassano and de Beaufort (1) discovered that the growth of certain phages was inhibited by the presence of citrate in the culture medium, and that this inhibition could be overcome by the addition of calcium salts. Bordet and Renaux (2) investigated a strain of Shiga phage which was unable to lyse the host cells in the presence ...

In vitro initiation of coliphage T7 mRNA
Archives of Biochemistry and Biophysics, 1972Abstract The synthesis of two classes of late T7 proteins appears to be directed by several polycistronic messenger RNAs. To understand how they are translated in appropriate order during phage infection, we have isolated late mRNA from T7-infected cells and mRNA that was synthesized in vitro with the T7 RNA polymerase and T7 DNA.

Transduction by coliphage λ of the galactose marker
Virology, 1957Abstract Phages obtained by induction of strain C600 Gal + made lysogenic for λ ++ when infecting strain 112 Gal − sensitive transduce Gal + with low frequency. The strain C600 Gal + is stable; it does not segregate Gal − . The transformed strains are “heterogenotes.” These heterogenotes have the following properties: 1. 1. They are Gal +

A genetic study of the temperate coliphage λ
Virology, 1955Abstract 1. 1. All the known markers in the temperate phage λ are linked to each other. 2. 2. Mating between pairs of intracellular particles occurs at random with respect to partner but is rather rare (average number of rounds of mating 0.5, assuming two reciprocal recombinants are formed simultaneously). 3. 3.
