Extreme sequence heteroplasmy in bat mitochondrial DNA.
Mitochondrial heteroplasmy is shown to be extensive when amplification products from the mitochondrial control region are cloned and sequenced from a European bat species. In contrast, a mitochondrial ribosomal RNA gene does not exhibit substantial levels of heteroplasmy when analyzed in an identical way. In the bat, heteroplasmy with respect to length as well as sequence seems to be transmitte...
متن کاملUniversal heteroplasmy of human mitochondrial DNA
Mammalian cells contain thousands of copies of mitochondrial DNA (mtDNA). At birth, these are thought to be identical in most humans. Here, we use long read length ultra-deep resequencing-by-synthesis to interrogate regions of the mtDNA genome from related and unrelated individuals at unprecedented resolution. We show that very low-level heteroplasmic variance is present in all tested healthy i...
متن کاملNucleotide sequence divergence in the A+T-rich region of mitochondrial DNA in Drosophila simulans and Drosophila mauritiana.
We have determined the nucleotide sequences of two regions within the A+T-rich region of mitochondrial DNA (mtDNA) in the siIII type of Drosophila simulans and the maI type of D. mauritiana. The sequences of the two regions in siIII and maI are almost identical. The sequences include elements corresponding to the type I and type II repeats elements and the T-stretches as reported in D. melanoga...
متن کاملInduction of mitochondrial DNA heteroplasmy by intra- and interspecific transplantation of germ plasm in Drosophila.
A new experimental system for inducing mitochondrial DNA heteroplasmy in Drosophila was developed. By transplanting the germ plasm of Drosophila melanogaster and Drosophila mauritiana into the posterior pole of the recipient eggs of D. melanogaster, it was possible to introduce foreign mitochondria into the recipient female germline. Heteroplasmic individuals containing both donor and recipient...
متن کاملComplete nucleotide sequence of the A+T-rich region of Drosophila mauritiana mitochondrial DNA.
We determined the complete nucleotide sequence of the A+T-rich region of the maII type of mtDNA in D. mauritiana. The nucleotide sequence was found to contain 3,206 bp. Three types of conserved element, i.e., type I element, type II element, and T-stretch, were included in this sequence, as reported for D. melanogaster. Comparison between the two species revealed that the type I elements were l...
