The entire nucleotide sequence of the mitochondrial genome of the American opossum, Didelphis virginiana, was determined. Two major features distinguish this genome from those of other mammals. First, five tRNA genes around the origin of light strand replication are rearranged. Second, the anticodon of tRNA(Asp) is posttranscriptionally changed by an RNA editing process such that its coding capacity is altered. When the complete protein-coding region of the mitochondrial genome is used as an…

Cloning and characterization of the platypus mitochondrial genome

The platypus mtDNA conforms to the basic chordate gene arrangement, common to fish, amphibians, and eutherian mammals, indicating that this arrangement was the original mammalian arrangement, and that the unusual rearrangements observed in the avians and marsupials are probably lineage-specific.

The mitochondrial genome of a monotreme—the platypus (Ornithrohynchus anatinus)

The complete nucleotide sequence of the mitochondrial genome of a platypus was determined and suggests that monotremes and marsupials are sister groups and thus that placental mammals represent the most ancient divergence among mammals.

The Complete Mitochondrial Genome of Rhea americana and Early Avian Divergences

Phylogenetic analysis of the complete cytochrome b genes of seven avian orders placed the Passeriformes basal in the avian tree with the Struthioniformes among the remaining Neognathae, challenging the commonly accepted notion that the most basal avian divergence is that between the PalaeognathAE and NeognATHae.

Mitochondrial genome organization and vertebrate phylogenetics

With the advent of DNA sequencing techniques the organization of the vertebrate mitochondrial genome shows variation between higher taxonomic levels, and some new rearrangements seem to be typical of monophyletic groups and the use of data from these groups may be useful for answering phylogenetic questions involving vertebrate higherTaxonomic levels.

The evolution of mitochondrial genome structure and function in insects

Comparative analyses were undertaken to apply the information gained from the mitochondrial transcripts of Drosophila melanogaster to the mitochondrial structure and annotations of mt-genomes from the other insects, and suggest a 5' specific modification to the tRNA punctuation model for insect mitochondria.

Complete mitochondrial genome suggests diapsid affinities of turtles.

The results challenge the classic view of turtles as the only survivors of primary anapsid reptiles and imply that turtles might have secondarily lost their skull fenestration.

Complete nucleotide sequence of the mitochondrial genome of a salamander, Mertensiella luschani.

Housekeeping genes for phylogenetic analysis of eutherian relationships.

The analyses of the currently established sequences have helped examination of problematic parts in the eutherian tree at the same time as they caution against suggestions that have claimed that basal eutheria relationships have been conclusively settled.

The complete nucleotide sequence of the mitochondrial genome of the lungfish (Protopterus dolloi) supports its phylogenetic position as a close relative of land vertebrates.

The phylogenetic analyses of genes coding for tRNAs and proteins confirm the intermediate phylogenetic position of lungfish between ray-finned fishes and tetrapods.

The complete mitochondrial genome of Tupaia belangeri and the phylogenetic affiliation of scandentia to other eutherian orders.

The complete mitochondrial genome of Tupaia belangeri was determined and compared with full-length mitochondrial sequences of other eutherian orders described to date, and most of both the mitochondrial and the nuclear data point away from Scandentia as the closest extant relatives to primates.

Editing of a tRNA anticodon in marsupial mitochondria changes its codon recognition.

Direct sequencing as well as clones of the amplified cDNA indicated that about 50% of the cellular pool of pre-tRNA molecules for aspartic acid is edited, indicating that RNA editing occurs in mammalian mitochondria and can affect the anticodons of tRNAs.

Evolution of the cytochrome b gene of mammals.

Comparisons of these cytochrome b sequences support current structure-function models for this membrane-spanning protein, which suggests that the outer surface which includes the Qo redox center is more constrained than the remainder of the molecule, namely, the transmembrane segments and the surface that protrudes into the mitochondrial matrix.

Sequence and gene organization of mouse mitochondrial DNA

The pattern of mammalian evolution and the relative rate of molecular evolution.

The assumption of a star phylogeny that underlies Kimura's test for molecular evolutionary rate variation is shown to be invalid for eutherian mammals and excess variance in nucleotide or amino acid differences between mammalian orders is explained better by variation in divergence time than by variationIn evolutionary rate.

Heterogeneity of tempo and mode of mitochondrial DNA evolution among mammalian orders.

It is shown that the L-strand of human mitochondrial DNA has significantly higher C content and lower T and A contents than those of bovine and murids, which suggests that a directional mutation pressure which tends to change base composition has been operating in the human lineage.

The relative rate tests involving paralogous and orthologous genes provide no evidence of heterogeneity, among species, in the rate of evolution of the genes and demonstrates that molecular evolutionary rate does not depend on generation time.

Sequence and organization of the human mitochondrial genome

The complete sequence of the 16,569-base pair human mitochondrial genome is presented and shows extreme economy in that the genes have none or only a few noncoding bases between them, and in many cases the termination codons are not coded in the DNA but are created post-transcriptionally by polyadenylation of the mRNAs.
