Viewed through the lens of the genome it contains, the mitochondrion is of unquestioned
bacterial ancestry, originating from within the bacterial phylum α-Proteobacteria …

Background Comparative analyses have indicated that the mitochondrion of the last
eukaryotic common ancestor likely possessed all the key core structures and functions that …

Eukaryotic cells originated when an ancestor of the nucleated cell engulfed bacterial
endosymbionts that gradually evolved into the mitochondrion and the chloroplast. Soon after …

The mitochondrial respiratory chain is comprised of four different protein complexes (I–IV),
which are responsible for electron transport and generation of proton gradient in the …

Euglena gracilis is a metabolically flexible, photosynthetic, and adaptable free-living protist
of considerable environmental importance and biotechnological value. By label-free liquid …

The mitochondrion is an essential organelle for the production of cellular ATP in most
eukaryotic cells. It is extensively studied, including in parasitic organisms such as …

Land plants feature particularly complicated mitochondrial genomes. Plant mitochondrial
DNAs may be more than 100 times larger than those of animals and are structurally much …

The mitochondrion, derived in evolution from an α-proteobacterial progenitor, plays a key
metabolic role in eukaryotes. Mitochondria house the electron transport chain (ETC) that …

Many genes inherited from the α-proteobacterial ancestor of mitochondria have undergone
evolutionary transfer to the nuclear genome in eukaryotes. In some rare cases, genes have …
