Roseophage
A roseophage is a type of bacteriophage, a virus that replicates within bacteria and archaea. It specifically infects bacteria from the ''Roseobacter'' family (also called ''Rhodobacteraceae''), which are one of the major groups of bacteria found in the marine environment. Roseophages have narrow host ranges, which can be seen in the list of known phages, and are a virus mainly found in marine ecosystems like Pelagic zone, pelagic, Estuary, estuaries and coastal regions, at various depths. History Roseophages were first identified during studies examining microbial dynamics in ocean ecosystems. The initial discovery occurred in 1989, when researchers investigating marine bacterioplankton isolated a phage named Roseophage SIO1 from the coastal waters of California. Using filtration and electron microscopy, researchers revealed that this phage shared genetic similarities with some non-marine bacteriophages. In 2000, SIO1 was sequenced and was found to have significant similarities ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacteriophage
A bacteriophage (), also known informally as a phage (), is a virus that infects and replicates within bacteria. The term is derived . Bacteriophages are composed of proteins that Capsid, encapsulate a DNA or RNA genome, and may have structures that are either simple or elaborate. Their genomes may encode as few as four genes (e.g. Bacteriophage MS2, MS2) and as many as hundreds of genes. Phages replicate within the bacterium following the injection of their genome into its cytoplasm. Bacteriophages are among the most common and diverse entities in the biosphere. Bacteriophages are ubiquitous viruses, found wherever bacteria exist. It is estimated there are more than 1031 bacteriophages on the planet, more than every other organism on Earth, including bacteria, combined. Viruses are the most abundant biological entity in the water column of the world's oceans, and the second largest component of biomass after prokaryotes, where up to 9x108 virus, virions per millilitre have b ...
