A Population Phylogenetic View of Mitochondrial Heteroplasmy.
The mitochondrion has recently emerged as an active player in myriad cellular processes. Additionally, it was recently shown that >200 diseases are known to be linked to variants in mitochondrial DNA or in nuclear genes interacting with mitochondria. This has reinvigorated interest in its biology and population genetics. Mitochondrial heteroplasmy, or genotypic variation of mitochondria within ...
متن کاملMitochondrial Diversity and Phylogenetic Structure of Marghoz Goat Population
The genetic diversity and phylogenetic structure was analyzed in Marghoz goat population by mitochondrial DNA sequences. Phylogenetic analysis was carried out using hyper variable region 1 (968 bp) obtained form 40 animals. Marghoz goat proved to be extremely diverse (average haplotype diversity of 0.999) and the nucleotide diversity values 0.022. A total of 40 Marghoz goats were grouped into s...
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 کاملExtreme 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 کاملPolymorphism, heteroplasmy, mitochondrial fusion and diabetes.
Mitochondrial DNA (mtDNA) is highly susceptible to mutations that result in polymorphisms and diseases including diabetes. We analyzed heteroplasmy, polymorphisms related to diabetes, and complementation by fusogenic proteins. Cytoplast fusion and microinjection allow, defects in mutated mtDNA inside a heteroplasmic cell to be complemented by fusing two mitochondria via human fusogenic proteins...
