• Identification and characterisation of mitochondrial sequences integrated into the ovine nuclear genome

    Summary
    Mitochondrial DNA sequences are frequently transferred into the nuclear genome, generating nuclear mitochondrial DNA sequences. Here, we analysed, for the first time, NUMTs in the ovine genome. We obtained 760 alignment matches covering 513.8 kbp of the sheep nuclear genome. After a merging step, we identified 390 NUMT regions with a total length of ~720 kbp, representing 0.02% of the nuclear genome. We discovered copies of all mitochondrial regions and found that most NUMT regions are intergenic or intronic. Ovine NUMTs are mostly not transcribed. However, we identified within...
