DNA Bacteriophages01:26

DNA Bacteriophages

Bacteriophages, or phages, are viruses that specifically infect bacteria, utilizing their genetic material to hijack host cellular machinery for replication. DNA bacteriophages employ single-stranded DNA (ssDNA) or double-stranded DNA (dsDNA) genomes. These phages exhibit diverse replication strategies and host interactions, influencing their ecological roles and applications in biotechnology and medicine.ssDNA BacteriophagesssDNA phages, with their small genomes, utilize unique strategies to...
Transduction01:16

Transduction

Among the three main modes of HGT—transformation, conjugation, and transduction—transduction is unique in that it is mediated by bacteriophages, or bacterial viruses.Transduction occurs in two ways. Generalized transduction occurs during the lytic cycle of a bacteriophage infection. In this process, bacteriophages infect bacterial cells, replicate within them, and ultimately cause cell lysis, releasing newly assembled virions. Occasionally, random fragments of the bacterial genome are...

Bacteriophages of the Human Virome

Bacteriophages are found throughout the human body. They may even outnumber eukaryotic viruses, forming an important and dynamic component of the human virome. Indeed, phages represent the most abundant viral entities, with densities in the gut reaching up to 10⁹ particles per gram of fecal matter, and many belonging to orders such as Caudovirales and Microviridae, while a substantial proportion remains unclassified as viral “dark matter.”Lysogeny and Genetic ExchangeIn the gut, bacteriophages...

Area of Science:

  • Molecular Biology
  • Virology
  • Entomology

Background:

  • Alphavirus transducing systems (ATSs) are derived from RNA viruses (Togaviridae).
  • Sindbis virus-based ATSs are commonly used, but others exist.
  • ATSs utilize viral subgenomic promoters for gene expression.

Purpose of the Study:

  • To highlight the utility of ATSs in insect gene expression.
  • To explain the mechanisms of ATSs for protein expression and gene silencing.
  • To emphasize the role of ATSs in vector-pathogen research and disease control.

Main Methods:

  • Utilizing infectious cDNA clones of alphaviruses.
  • Engineering viral genomes to include genes of interest (GOI).
  • Positioning GOI 5' for stable protein expression or 3' for RNA interference (RNAi).

Main Results:

  • ATSs facilitate stable protein expression in insects when GOI is 5'.
  • ATSs enable gene silencing via RNAi when GOI is 3'.
  • ATSs are effective for studying vector-pathogen dynamics.

Conclusions:

  • ATSs are versatile tools for insect functional genomics.
  • These systems aid in understanding vector competence and disease transmission.
  • ATSs support informed decisions on gene-based vector control strategies.
