The evolution of giant virus genomes

Science, 2017
Viral Genomics Some giant viruses encode a genome larger than that of some bacteria, but their evolutionary history is a mystery. Examining the genomes within a sample from a wastewater treatment plant in Austria, Schulz et al. assembled a previously undiscovered giant virus genome, which they used to mine genetic databases for related viruses.

The Variety of Human Virus Evolution

Molecular Phylogenetics and Evolution, 1996
There have been many wise suggestions of ways that evolution may occur but those ways seem often hard to support with good examples. Viruses have proven to be replete with some of these items. This paper reviews work that shows: (1) very fast rates of evolution; (2) positive Darwinian selection with the selective pressure specifically identified; (3 ...

Evolution of infectious salmon anaemia virus (ISA virus)

Archives of Virology, 2012
Infectious salmon anaemia virus, ISA virus (genus Isavirus, family Orthomyxoviridae), emerged in Norwegian salmon culture in the mid-80s. The genome consists of eight segments coding for at least 10 proteins. ISA viruses show many of similarities to influenza A viruses but differ in many important aspects such as the number of hosts, the host ...

Persistent infection with influenza A virus: Evolution of virus mutants

Virology, 1984
A persistent infection (persistent infection I) of baby hamster kidney (BHK) cells with the WSN (H1N1) strain of influenza A virus was established using a virus stock which contained a high proportion of defective-interfering (DI) particles. Virus recovered from passage 92 (388 days) of persistent infection I was used to establish a second persistent ...

The Evolution of Bluetongue Virus Serotype 17

The American Journal of Tropical Medicine and Hygiene, 1983
Four serotypes of bluetongue virus (BTV-10, 11, 13 and 17) have been identified in the United States. Analyses of the genome RNA segments and viral induced polypeptides of U.S. prototype BTV-17 virus by comparison with the corresponding macromolecules of earlier isolates of BTV-11 serotype support the hypothesis that BTV-17 originated by genotypic and ...

[Virus and evolution].

Nederlands tijdschrift voor geneeskunde, 2010
Viruses have long been held to be derailed cellular elements with a parasitic replication cycle: since without a cell there is no virus. However, the explosion in recently acquired molecular data from genome and protein sequences leads to a completely different view: viruses contain sequences which are unique in the biosphere, which is difficult to ...

Virus Evolution and the Beginning

Zeitschrift für anorganische und allgemeine Chemie, 2009
AbstractWe assume the pentagonal viruses are relatively late and search for models of an earlier evolution. A possible start from the beginning billions of years ago would be cubic mathematics describing hypothetical virus structures. The proposed shift from cubic to pentagonal symmetry is unique and methods from inorganic solid‐state chemistry are ...

Virus, Evolution, Urzeugung

1964
Am Ende unseres Diskurses uber das scheinbar sehr spezielle, in Wirklichkeit jedoch zur Beantwortung fundamentalster Fragen der Biologie hinfuhrende Virusproblem durfen wir wohl getrost zu wissen behaupten, was Virus ist. Sind wir aber deshalb in der Lage, unser Wissen in knappen Worten auszudrucken?
