Conservative Site-specific Recombination and Phase Variation02:53

Conservative Site-specific Recombination and Phase Variation

Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...
In-vitro Mutagenesis01:16

In-vitro Mutagenesis

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.

Area of Science:

  • Molecular Biology
  • Mycology
  • Genetics

Background:

  • High-throughput gene deletion methods are needed for fungal genomics.
  • Existing methods can be time-consuming and complex.

Purpose of the Study:

  • To develop a fast, simple, and universal method for generating fungal gene deletion constructs.
  • To establish a robust protocol for creating precise deletion mutants.

Main Methods:

  • Utilized Polymerase Chain Reaction (PCR) and Gateway cloning technology.
  • Employed the I-SceI homing endonuclease for construct generation.
  • Developed a modified Gateway vector with selectable markers for fungal transformation.

Main Results:

  • The DelsGate method generates deletion constructs in just 2 days.
  • Successfully created deletion constructs for 12 Ustilago maydis genes.
  • Empirically determined 1 kb as a suitable flank length for homologous recombination.

Conclusions:

  • DelsGate offers a universal, simple, and robust approach for fungal gene deletion.
  • The method is well-suited for high-throughput applications in various fungal species.
  • DelsGate facilitates the creation of precise deletion mutants efficiently.
