Insights

The Mypoviridae family comprises negative-sense RNA viruses discovered in myriapods. Their genome structure includes three RNA segments encoding key viral proteins like nucleoprotein and RNA-directed RNA polymerase.

Area of Science:

  • Virology
  • Myriapod biology
  • RNA virus taxonomy

Background:

  • Mypoviridae is a family of negative-sense RNA viruses.
  • These viruses have been identified in myriapods.
  • Their genomes are approximately 16.0 kb in size.

Purpose of the Study:

  • To summarize the International Committee on Taxonomy of Viruses (ICTV) report on the family Mypoviridae.
  • To provide an overview of the Mypoviridae family's characteristics.
  • To document the classification and features of these myriapod-associated viruses.

Main Methods:

  • Review and summarization of the official ICTV report.
  • Analysis of the genomic structure of Mypoviridae.
  • Description of the encoded proteins, including nucleoprotein (NP), glycoprotein (GP), and large (L) protein.

Main Results:

  • Mypoviridae genomes consist of three monocistronic RNA segments.
  • These segments encode essential viral proteins: nucleoprotein (NP), glycoprotein (GP), and a large (L) protein.
  • The L protein contains a crucial RNA-directed RNA polymerase (RdRP) domain.

Conclusions:

  • The Mypoviridae family represents a distinct group of RNA viruses found in myriapods.
  • Understanding their genome organization is key to viral classification.
  • This summary serves as a reference for the Mypoviridae family based on the ICTV report.

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

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...

Retroviruses02:33

Retroviruses

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’...

Viral Recombination00:57

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Viral Mutations00:36

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Viral Structure00:56

Viral Structure

Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.
