Origin of a New Testes Gene in Drosophila
Author Information
Author(s): Arguello J. Roman, Chen Ying, Yang Shuang, Wang Wen, Long Manyuan
Primary Institution: University of Chicago
Hypothesis
How does illegitimate recombination contribute to the formation of new gene functions in Drosophila?
Conclusion
The study identifies a young chimeric gene in Drosophila that evolved through illegitimate recombination and has developed testes-specific expression.
Supporting Evidence
- The new gene evolved testes-specific expression.
- Evidence for positive selection was found along the D. simulans branch.
- The gene was created within the last 2–3 million years.
Takeaway
Scientists found a new gene in fruit flies that was created by mixing parts of other genes, and this new gene helps with reproduction.
Methodology
The study used fluorescent in situ hybridization, Southern analysis, and genomic amplification to identify and verify the gene duplication.
Limitations
The functionality of the gene in D. sechellia and D. mauritiana is uncertain due to the presence of premature stop codons.
