Introduction to Virus

1.4K
Viruses are unique biological entities that blur the boundary between living and non-living systems. Although they lack cellular structure and metabolic processes, they can exhibit characteristics of life when infecting a host. Their defining feature is a nucleic acid core, composed of either DNA or RNA, encapsulated within a protein coat called a capsid. This simple structure allows them to invade host cells and use their machinery for replication efficiently.Viral Structure and...

Viruses of Archaea

473
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

869
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...

Intracellular Movement of Viruses and Bacteria

3.5K
Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a...

Rous Sarcoma Virus (RSV) and Cancer

6.2K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Summary

This review explores understudied viruses within the plant-associated environment (phytobiome). It highlights viruses in soil, wild plants, and their interactions with microbes and vectors.

Area of Science:

  • * Phytobiome Virology: Investigating viral communities within plant-associated ecosystems.

Background:

  • * The phytobiome, encompassing plants and interacting organisms, harbors diverse viruses.
  • * Most phytobiome viruses, beyond those affecting crops, are poorly understood.
  • * Existing research predominantly focuses on viruses of cultivated plants.

Purpose of the Study:

  • * To review and highlight understudied viral components of the phytobiome.
  • * To focus on viruses associated with non-crop plants and soil environments.
  • * To explore virus interactions with other microbes and vectors within the phytobiome.

Main Methods:

  • * Comprehensive literature review of phytobiome virology.
  • * Synthesis of data on viruses in soil, wild plants, and microbial communities.

  • * Analysis of virus-vector relationships in plant-associated environments.

    • Main Results:

    • * Significant viral diversity exists beyond crop-infecting viruses.
    • * Viruses associated with soil and wild plants remain largely uncharacterized.
    • * Interactions between viruses, microbes, and vectors are crucial but understudied.

    Conclusions:

    • * There is a critical need for increased research into neglected phytobiome viruses.
    • * Understanding these viruses is essential for a holistic view of plant health and ecosystem function.
    • * Future research should encompass soil virology, wild plant viruses, and virus-vector dynamics.
