Abstract

At concentrations of approximately 10 7 viruses per milliliter of surface water, viruses are the most abundant biological entities in the oceans. Through lysing their bacterial hosts, marine phages control bacterial abundances and impact global biogeochemical cycles. Phages influence their hosts through cell lysis, DNA transfer and manipulation of host gene expression and metabolism. Also, phages influence the remaining community through the release of dissolved organic matter, the introduction to novel genetic material and the selection for resistance. Marine viruses are extremely diverse and represent reservoir of ocean genetic diversity. Over the past two decades, marine virology has progresed from curiosity to a well-established scinetific field. In the future, marine virology has the potential to inform numerous other fields, ranging from ecology of other ecosystems (e.g. freswater, terrestrial) to medicine (e.g. human microbiome).
