Expression of catalytic mutants of the mtDNA helicase Twinkle and polymerase POLG causes distinct replication stalling phenotypes. [PDF]

, 2007
The mechanism of mitochondrial DNA replication is a subject of intense debate. One model proposes a strand-asynchronous replication in which both strands of the circular genome are replicated semi-independently while the other model proposes both a ...

A new method for long-read sequencing of animal mitochondrial genomes: application to the identification of equine mitochondrial DNA variants

BMC Genomics, 2020
Background Mitochondrial DNA is remarkably polymorphic. This is why animal geneticists survey mitochondrial genomes variations for fundamental and applied purposes.

G-Quadruplex Dynamics Contribute To Regulation Of Mitochondrial Gene Expression [PDF]

, 2019
Single-stranded DNA or RNA sequences rich in guanine (G) can adopt non-canonical structures known as G-quadruplexes (G4). Mitochondrial DNA (mtDNA) sequences that are predicted to form G4 are enriched on the heavy-strand and have been associated with ...

Structure–Function Analysis Reveals the Singularity of Plant Mitochondrial DNA Replication Components: A Mosaic and Redundant System

Plants, 2019
Plants are sessile organisms, and their DNA is particularly exposed to damaging agents. The integrity of plant mitochondrial and plastid genomes is necessary for cell survival.

Extensive Structural Variations Between Mitochondrial Genomes of CMS and Normal Peppers (Capsicum Annuum L.) Revealed by Complete Nucleotide Sequencing [PDF]

, 2014
Cytoplasmic male sterility (CMS) is an inability to produce functional pollen that is caused by mutation of the mitochondrial genome. Comparative analyses of mitochondrial genomes of lines with and without CMS in several species have revealed structural ...

Mitochondrial DNA and ageing

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2006
The accumulation of mitochondrial DNA mutations has been proposed as a potential mechanism in the physiological processes of ageing and age-related disease. Although mitochondria have long been anticipated as a perpetrator of ageing, there was little experimental evidence to link these changes directly with the cellular pathology of ageing.
