Summary
Konkoviridae are plant-infecting negative-sense RNA viruses. Their genomes are segmented and encode proteins essential for viral replication and movement.
Area of Science:
- Virology
- Plant Pathology
- Molecular Biology
Background:
- Konkoviridae is a family of negative-sense RNA viruses.
- These viruses infect plants and have filamentous virions shaped like kinked circles.
- Their genomes range from 8.7-10.6 kilobases.
Purpose of the Study:
- To summarize the International Committee on Taxonomy of Viruses (ICTV) report on the family Konkoviridae.
- To provide an overview of the taxonomy and characteristics of konkoviruses.
Main Methods:
- Review and summarization of the ICTV Report on Konkoviridae.
- Analysis of genomic and virion structure information.
Main Results:
- Konkovirus genomes comprise 3-4 segments.
- Open reading frames (ORFs) encode a large protein (L) with RNA-directed RNA polymerase activity, a nucleoprotein, a movement protein, and non-structural proteins.
- Virions are filamentous and possess a kinked circle morphology.
Conclusions:
- The ICTV report provides a comprehensive taxonomic overview of the Konkoviridae family.
- Understanding konkovirus genome organization and protein functions is crucial for plant virus research.

01:29Viruses with RNA Genomes
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...
01:25Inhibitors Of Virion Release
Viral replication and dissemination rely on efficient mechanisms for host cell entry, genome replication, assembly, and release. Influenza viruses, such as types A and B, are negative-sense single-stranded RNA viruses with a segmented genome, that depend on two critical surface glycoproteins to carry out these processes: hemagglutinin (HA) and neuraminidase (NA). HA initiates infection by binding to sialic acid residues on the surface of host epithelial cells, facilitating receptor-mediated...

Overview
01:10Retrovirus 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 retrovirus to...
01:29Subviral Agents
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...
01:29Viruses of Archaea
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...
