The mitochondrion is deemed to be one of the most important organelles, and plays an essential role in various biological processes. Nonetheless, the role of mitochondria in response to abiotic stress remains unclear. Here, we report that accumulation of the cytoplasmic male sterility (CMS) protein ORFH79 in the vegetative tissues resulted in the dysfunction of mitochondria with decreased enzym...

Mitochondrial DNA (mtDNA) mutations frequently cause neurological diseases. Modeling of these defects has been difficult because of the challenges associated with engineering mtDNA. We show here that neural progenitor cells (NPCs) derived from human induced pluripotent stem cells (iPSCs) retain the parental mtDNA profile and exhibit a metabolic switch toward oxidative phosphorylation. NPCs deri...

Phlebiopsis gigantea (Fr.) Jülich is a well-known generalist conifer wood saprobe and biocontrol fungus used in several world countries to prevent stump infection by tree pathogenic Heterobasidion fungal species. Previous studies have reported the presence of regional continental genetic differentiation host-specific fungi, but such for saprobes as P. has not been often studied or demonstrated....

The nucleotide sequence for 40,469 bp of the linear Paramecium aurelia mitochondrial (mt) genome is presented with the locations of the known genes, presumed ORFs, and their transcripts. Many of the genes commonly encoded in mt DNA of other organisms have been identified in the Paramecium mt genome but several unusual genes have been found. Ribosomal protein genes rps14, rps12, and rpl2 are clu...

Organismal fitness requires functional integration of nuclear and mitochondrial genomes. Structural and regulatory elements coevolve within lineages and several studies have found that interpopulation hybridization disrupts mitonuclear interactions. Because mitochondrial RNA polymerase (mtRPOL) plays key roles in both mitochondrial DNA (mtDNA) replication and transcription, the interaction betw...

We sequenced and compared the mitogenome organization of two specimens of suboscine tyrant flycatcher Mionectes oleagineus from western and eastern Panama, representing distinct mtDNA clades. These samples show identical gene arrangement and vary in size by less than 5 base pairs. Both depict a non-standard avian gene order with an extra non-coding region (e.g. the remnant CR2), which differs i...

Rhodactina is a small sequestrate genus in Boletaceae with two described species, R. himalayensis and R. incarnata. Phylogenetic analyses of a three-gene dataset including atp6, tef1 and rpb2 of Rhodactina species along with selected Boletaceae species showed that all Rhodactina species formed a monophyletic clade, sister to the genera Spongiforma and Borofutus in subfamily Leccinoideae with hi...

We applied the RFLP approach to identify the cytoplasmic genotypes of selected onion breeding materials from Poland. For this purpose, mitochondrial DNA from cytoplasmic male-sterile (CMS) and male-fertile onions were hybridized with the probes for the following mitochondrial genes: atpA, atp6, atp9, cob, cox1, nad3, nad4 and nad6. S-, T- or C-cytoplasm was represented in each analyzed sterile ...
