Mitochondrial plastid DNA can cause DNA barcoding paradox in plants [PDF]

Scientific Reports, 2020
AbstractThe transfer of ancestral plastid genomes into mitochondrial genomes to generate mitochondrial plastid DNA (MTPT) is known to occur in plants, but its impacts on mitochondrial genome complexity and the potential for causing a false-positive DNA barcoding paradox have been underestimated.

Oxidative and Glycation Damage to Mitochondrial DNA and Plastid DNA during Plant Development

Antioxidants, 2023
Oxidative damage to plant proteins, lipids, and DNA caused by reactive oxygen species (ROS) has long been studied. The damaging effects of reactive carbonyl groups (glycation damage) to plant proteins and lipids have also been extensively studied, but only recently has glycation damage to the DNA in plant mitochondria and plastids been reported.

Ribonucleotide and R-Loop Damage in Plastid DNA and Mitochondrial DNA during Maize Development

Plants, 2023
Although the temporary presence of ribonucleotides in DNA is normal, their persistence represents a form of DNA damage. Here, we assess such damage and damage defense to DNA in plastids and mitochondria of maize. Shoot development proceeds from meristematic, non-pigmented cells containing proplastids and promitochondria at the leaf base to non-dividing

New Insights into the Diversity of Mitochondrial Plastid DNA. [PDF]

Genome Biol Evol
Abstract The mitochondrial plastid DNAs (MTPTs) in seed plants were reported more than 40 years ago and exhibited a high diversity regarding gene content, quantity, and size. However, the mechanism that resulted in the current diversity of MTPTs in angiosperms has not been fully discovered.

Evidence for horizontal transfer of mitochondrial DNA to the plastid genome in a bamboo genus [PDF]

Scientific Reports, 2015
AbstractIn flowering plants, three genomes (nuclear, mitochondrial and plastid) coexist and intracellular horizontal transfer of DNA is prevalent, especially from the plastid to the mitochondrion genome. However, the plastid genomes are generally conserved in evolution and have long been considered immune to foreign DNA.

The mitochondrial and plastid genomes of Volvox carteri: bloated molecules rich in repetitive DNA [PDF]

BMC Genomics, 2009
The magnitude of noncoding DNA in organelle genomes can vary significantly; it is argued that much of this variation is attributable to the dissemination of selfish DNA. The results of a previous study indicate that the mitochondrial DNA (mtDNA) of the green alga Volvox carteri abounds with palindromic repeats, which appear to be selfish elements.

Against the traffic [PDF]

Mobile Genetic Elements, 2012
Transfer of DNA between different compartments of the plant cell, i.e., plastid, mitochondrion and nucleus, is a well-known phenomenon in plant evolution. Six directions of inter-compartmental DNA migration are possible in theory, however only four of them have been previously reported.

Unprecedented organelle genomic variations in morning glories reveal independent evolutionary scenarios of parasitic plants and the diversification of plant mitochondrial complexes

BMC Biology, 2022
Background The morning glories (Convolvulaceae) are distributed worldwide and produce economically important crops, medicinal herbs, and ornamentals. Members of this family are diverse in morphological characteristics and trophic modes, including the ...

Changes in DNA damage, molecular integrity, and copy number for plastid DNA and mitochondrial DNA during maize development [PDF]

Journal of Experimental Botany, 2014
The amount and structural integrity of organellar DNAs change during plant development, although the mechanisms of change are poorly understood. Using PCR-based methods, we quantified DNA damage, molecular integrity, and genome copy number for plastid and mitochondrial DNAs of maize seedlings. A DNA repair assay was also used to assess DNA impediments.
