In-vitro Mutagenesis

15.9K
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Transgenic Plants

8.3K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Area of Science:

  • Avian biology
  • Genomics
  • Biomedical research models

Background:

  • Chicken embryos are valuable but have a long generation time, limiting their use in research.
  • Japanese quail are similar to chickens but mature much faster (1.5 months vs. 6 months).
  • Existing transgenic quail methods using lentiviruses have limitations.

Purpose of the Study:

  • To introduce a novel, efficient transgenesis technology for Japanese quail.
  • To overcome limitations of previous transgenic methods in quail.
  • To facilitate genome editing and collaborative research in avian models.

Main Methods:

  • In vivo transfection of plasmids into circulating Primordial Germ Cells (PGCs) in Japanese quail.
  • Development of a website for quail genomic and technological information.
  • Showcasing past and future transgenic quail lines.

Main Results:

  • A simple and efficient method for quail transgenesis was established.
  • The technique allows for diverse genome engineering approaches.
  • A centralized website was launched to support the avian research community.

Conclusions:

  • This novel plasmid-based in vivo transfection method significantly improves quail transgenesis.
  • The technology accelerates the use of quail as a practical biomedical research model.
  • The accompanying website fosters collaboration and advances avian genome editing strategies.
