Viruses of Archaea01:29

Viruses of Archaea

74
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

110
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...

Three-Domain System of Life

204
Ribosomal RNA (rRNA) sequence analysis revealed three distinct groups of cells: eukaryotes, bacteria, and archaea. In 1978, Carl R. Woese proposed the concept of domains, a taxonomic level above kingdoms, to differentiate these groups. He suggested that archaea and bacteria, despite their similar appearance, represent separate domains. Domains differ in rRNA, membrane lipid structure, transfer RNA, and antibiotic sensitivity.In this classification, animals, plants, and fungi belong to the...

RNA Interference01:23

RNA Interference

26.4K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

Types of RNA01:23

Types of RNA

Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Ribozymes02:47

Ribozymes

12.4K
The term ribozyme is used for RNA that can act as an enzyme. Ribozymes are mainly found in selected viruses, bacteria, plant organelles, and lower eukaryotes. Ribozymes were first discovered in 1982 when Tom Cech’s laboratory observed Group I introns acting as enzymes. This was shortly followed by the discovery of another ribozyme, Ribonulcease P, by Sid Altman’s laboratory. Both Cech and Altman received the Nobel Prize in chemistry in 1989 for their work on ribozymes.

Area of Science:

  • Marine Biology
  • Virology
  • Invertebrate Zoology

Background:

  • Echinoderms are ecologically and economically important marine invertebrates.
  • The RNA virome of echinoderms remains largely uncharacterized compared to other invertebrates.

Purpose of the Study:

  • To characterize the diversity of RNA viruses infecting echinoderms.
  • To investigate viral representation across different echinoderm life stages.

Main Methods:

  • Screening of over 900 transcriptomes and viral metagenomes.
  • Analysis of 38 echinoderm species from all five classes.
  • Classification of viral genome fragments to genera and families within nine viral orders.

Main Results:

  • Identification of 347 viral genome fragments from nine viral orders.
  • Viral representation did not significantly differ between embryonic, larval, and adult stages.
  • Most viral contigs were identified in adult echinoderm tissues.

Conclusions:

  • This study reveals significant RNA virus biodiversity within echinoderm populations.
  • It highlights the presence of diverse viral groups in these marine invertebrates.
  • The findings contribute to understanding marine viromes and invertebrate-host interactions.
