The ecological consequences and evolution of retron-mediated suicide as a way to protect Escherichia coli from being killed by phage
The models and experiments demonstrate that cells expressing a retron-mediated abortive infection system can protect bacterial populations and demonstrate that retron bearing bacteria only have a competitive advantage under a limited set of conditions.
Half a century of the reverse transcriptase—happy birthday!
The reverse transcriptase (RT) was discovered 50 years ago by Howard M. Temin, Satoshi Mitzutani, and David Baltimore, and the name retrovirus is based on the RT, allowing the unexpected flow of genetic information from RNA to DNA, which was considered to be reversed when it was discovered in 1970.
Multi-copy single-stranded DNA in Escherichia coli.
Insight is provided into the molecular biosynthesis, distribution and function of E. coli msDNA to raise awareness about these special molecules.
Engineering a Bacterial Tape Recorder
A method has been developed to produce and integrate single‐stranded DNA into genomic locations in bacteria in response to exogenous signals, and the scalability and recording capacity have been improved over previous designs.
Optimisation of Banana streak virus (BSV) diagnostic assays
Bananas are one of the world�fs most important crops, serving as a staple food and an important source of income for millions of people in the subtropics. Pests and diseases are a major constraint to
The Role of Bacteria and Yeasts in AIDS
Molecular evolution of mobile elements of the gypsy group: A homolog of the gag gene in Drosophila
It can be concluded that homologous genes of all components of gypsy retrotransposons are present in the Drosophila genome.
Evolution of Teleost Fish Retroviruses: Characterization of New Retroviruses with Cellular Genes
Eleven new species of fish retroviruses are identified and characterized, significantly expanding the epsilonretrovirusFamily, which began infecting fish genomes approximately 4 million years ago.

Reexamination of the genome size of myxobacteria, including the use of a new method for genome size analysis
The genome sizes of two myxobacteria, Myxococcus xanthus and Stigmatella aurantiaca, were measured by renaturation analysis and also by a new method involving the quantitation of individual restriction fragments, which indicated that the M.xanthus genome is only about 24 to 53% larger than that of E. coli.

A specific acquired somatic characteristic in the immune system (tolerance to major histocompatibility antigens) induced in male mice shows significant transmission to first- and second-generation offspring.
Origins and Evolutionary Relationships of Retroviruses
Computer alignment of all these sequences allows an overall phylogeny to be constructed that chronicles the history of events leading to infectious retroviruses.
Nonviral retroposons: genes, pseudogenes, and transposable elements generated by the reverse flow of genetic information.
The Viral Supeifamily, The Viral Superfamily, and The Nonviral Superfamily: A Functional Semiprocessed Retrogene are presented.
