Viruses of Archaea01:29

Viruses of Archaea

391
Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

Viruses with RNA Genomes

624
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

49.0K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Retroviruses

14.5K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Subviral Agents01:29

Subviral Agents

403
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Area of Science:

  • Microbiology
  • Virology
  • Bacteriology

Background:

  • The family Herelleviridae includes bacterial viruses known as bacteriophages.
  • These viruses specifically infect bacteria belonging to the phylum Firmicutes.
  • Understanding bacteriophage taxonomy is crucial for fields like microbial ecology and biotechnology.

Purpose of the Study:

  • To summarize the official classification and characteristics of the family Herelleviridae.
  • To provide an accessible overview of the ICTV Report on Herelleviridae.
  • To establish a clear taxonomic framework for these bacterial viruses.

Main Methods:

  • Review and synthesis of the International Committee on Taxonomy of Viruses (ICTV) report.
  • Analysis of morphological characteristics of Herelleviridae virions.
  • Characterization of the genetic material (dsDNA genome size) of these viruses.

Main Results:

  • Herelleviridae viruses exhibit myovirus morphology.
  • Their genomes consist of linear double-stranded DNA (dsDNA).
  • Genome sizes range from 125 to 170 kilobase pairs (kb).
