    Gene transposition as a cause of hybrid sterility in Drosophila (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-09-09
    Description: We describe reproductive isolation caused by a gene transposition. In certain Drosophila melanogaster-D. simulans hybrids, hybrid male sterility is caused by the lack of a single-copy gene essential for male fertility, JYAlpha. This gene is located on the fourth chromosome of D. melanogaster but on the third chromosome of D. simulans. Genomic and molecular analyses show that JYAlpha transposed to the third chromosome during the evolutionary history of the D. simulans lineage. Because of this transposition, a fraction of hybrids completely lack JYAlpha and are sterile, representing reproductive isolation without sequence evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Masly, John P -- Jones, Corbin D -- Noor, Mohamed A F -- Locke, John -- Orr, H Allen -- New York, N.Y. -- Science. 2006 Sep 8;313(5792):1448-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Rochester, Rochester, NY 14627, USA. msly@mail.rochester.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16960009" target="_blank"〉PubMed〈/a〉

    A single gene causes both male sterility and segregation distortion in Drosophila hybrids (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-12-17
    Description: A central goal of evolutionary biology is to identify the genes and evolutionary forces that cause speciation, the emergence of reproductive isolation between populations. Despite the identification of several genes that cause hybrid sterility or inviability-many of which have evolved rapidly under positive Darwinian selection-little is known about the ecological or genomic forces that drive the evolution of postzygotic isolation. Here, we show that the same gene, Overdrive, causes both male sterility and segregation distortion in F1 hybrids between the Bogota and U.S. subspecies of Drosophila pseudoobscura. This segregation distorter gene is essential for hybrid sterility, a strong reproductive barrier between these young taxa. Our results suggest that genetic conflict may be an important evolutionary force in speciation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2628965/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2628965/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Phadnis, Nitin -- Orr, H Allen -- GM51932/GM/NIGMS NIH HHS/ -- R01 GM051932/GM/NIGMS NIH HHS/ -- R01 GM051932-13/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Jan 16;323(5912):376-9. doi: 10.1126/science.1163934.
