Abstract

2015 marks the centennial of the discovery of bacteriophages, viruses that infect bacteria. Phages have been central to some of biology's most meaningful advances over the past hundred years (shown here); they greatly influence the workings of the biosphere, and are poised to play expanded roles in biomedicine, biotechnology, and ecology.

Marine viruses and global climate change.

Roberto Danovaro, Cinzia Corinaldesi, Jack Middelburg … (2011)

Sea-surface warming, sea-ice melting and related freshening, changes in circulation and mixing regimes, and ocean acidification induced by the present climate changes are modifying marine ecosystem structure and function and have the potential to alter the cycling of carbon and nutrients in surface oceans. Changing climate has direct and indirect consequences on marine viruses, including cascading effects on biogeochemical cycles, food webs, and the metabolic balance of the ocean. We discuss here a range of case studies of climate change and the potential consequences on virus function, viral assemblages and virus-host interactions. In turn, marine viruses influence directly and indirectly biogeochemical cycles, carbon sequestration capacity of the oceans and the gas exchange between the ocean surface and the atmosphere. We cannot yet predict whether the viruses will exacerbate or attenuate the magnitude of climate changes on marine ecosystems, but we provide evidence that marine viruses interact actively with the present climate change and are a key biotic component that is able to influence the oceans' feedback on climate change. Long-term and wide spatial-scale studies, and improved knowledge of host-virus dynamics in the world's oceans will permit the incorporation of the viral component into future ocean climate models and increase the accuracy of the predictions of the climate change impacts on the function of the oceans. © 2010 Federation of European Microbiological Societies.

Exploring the prokaryotic virosphere.

Debbie Lindell, N Mann, David Prangishvili … (2008)

The world of prokaryotic viruses, including the "traditional" bacteriophages and the viruses of Archaea, is currently in a period of renaissance, brought about largely by our new capabilities in (meta)genomics and by the isolation of diverse novel virus-host systems. In this review, we highlight some of the directions where we believe research on the prokaryotic virosphere will lead us in the near future.

Bacteriophage-based synthetic biology for the study of infectious diseases.

Robert J. Citorik, Mark Mimee, Timothy K. Lu (2014)

Since their discovery, bacteriophages have contributed enormously to our understanding of molecular biology as model systems. Furthermore, bacteriophages have provided many tools that have advanced the fields of genetic engineering and synthetic biology. Here, we discuss bacteriophage-based technologies and their application to the study of infectious diseases. New strategies for engineering genomes have the potential to accelerate the design of novel phages as therapies, diagnostics, and tools. Though almost a century has elapsed since their discovery, bacteriophages continue to have a major impact on modern biological sciences, especially with the growth of multidrug-resistant bacteria and interest in the microbiome.
