Summary
This study details standard crossing methods for Schizosaccharomyces pombe, a fission yeast. It covers strain recording, mating induction on specific media, and protoplast fusion for sterile mutants to facilitate genetic crosses.
Area of Science:
- Microbiology
- Genetics
- Molecular Biology
Background:
- Standardized genetic crosses are essential for research in Schizosaccharomyces pombe.
- Efficient mating protocols are crucial for genetic analysis and strain development.
Purpose of the Study:
- To provide detailed methods for setting up standard crosses with Schizosaccharomyces pombe strains.
- To outline techniques for overcoming challenges in yeast mating and zygote formation.
Main Methods:
- Induction of mating between haploid Schizosaccharomyces pombe strains on nitrogen-poor solid medium.
- Utilization of sporulation agar (SPA) plates and testing of alternative mating media for optimal efficiency.
- Application of protoplast fusion for generating zygotes from sterile mutants that exhibit mating deficiencies.
Main Results:
- Established protocols for successful standard crosses in Schizosaccharomyces pombe.
- Demonstrated the efficacy of various media and protoplast fusion in achieving efficient mating and zygote formation.
Conclusions:
- The provided methods facilitate reliable genetic crosses in Schizosaccharomyces pombe.
- These techniques are valuable for researchers studying yeast genetics and performing genetic analysis.

Crossing Over
172.7K
Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...

Crossing Over
6.8K
Crossing over is the exchange of genetic information between homologous chromosomes during prophase I of meiosis I. Genetic recombination gives rise to allelic diversity in the newly formed daughter cells. In humans, crossing over produces genetically distinct haploid egg and sperm cells that undergo fertilization to produce unique offspring. Before cell division starts, the germ cell’s chromosome(s) undergo duplication in the S phase of the cell cycle. As the cells enter prophase I,...
