With the polymerase chain reaction (PCR) and versatile primers that amplify the whole cytochrome b gene (approximately 1140 bp), we obtained 17 complete gene sequences representing three orders of hoofed mammals (ungulates) and dolphins (cetaceans). The fossil record of some ungulate lineages allowed estimation of the evolutionary rates for various components of the cytochrome b DNA and amino acid sequences. The relative rates of substitution at first, second, and third positions within codons… 
c-Myc Gene Sequences and the Phylogeny of Bats and Other Eutherian Mammals
TLDR
The complete protein-coding sequences of the c-myc proto-oncogene were determined for four new orders of eutherian (placental) mammals and provided clear support for the grouping of Chiroptera (bats) with Artiodactyla (ruminants, camels, and pigs) and Carnivora (cats, dogs, and their allies), an interordinal arrangement that receives strong corroboration from other lines of evidence including complete mitochondrial DNA sequences.
Evolution of the mitochondrial DNA control region and cytochrome b genes and the inference of phylogenetic relationships in the avian genus Lophura (Galliformes).
TLDR
A conventional calibration of mtDNA sequence divergence indicates a mid to late Pliocene evolution of the main clades in Lophura, which could have diversified in allopatry in continental South East Asia.
Sequence evolution and phylogenetic signal in control-region and cytochrome b sequences of rainbow fishes (Melanotaeniidae).
TLDR
It is deduced that both the control region and cytochrome b are appropriate for population genetic studies but that the control area is less effective than cy tochrome b for resolving relationships among divergent lineages of rainbow fishes.
Mammalian mitochondrial DNA evolution: A comparison of the cytochrome b and cytochrome c oxidase II genes
TLDR
The evolution of two mitochondrial genes, cytochrome b and cy tochrome c oxidase subunit II, was examined in several eutherian mammal orders, with special emphasis on the orders Artiodactyla and Rodentia, where neither gene performed with a high degree of consistency in terms of the phylogenetic hypotheses supported.
Mitochondrial DNA-like sequence in the nuclear genome of an akodontine rodent.
TLDR
When probed with both functional and nonfunctional gene fragments, MboI restriction digests revealed the same pattern, providing further evidence that the nonfunctional copy must be located in the nucleus.
Accelerated Evolution of Cytochrome b in Simian Primates: Adaptive Evolution in Concert with Other Mitochondrial Proteins?
TLDR
It is proposed that the evolutionary rate increase observed for cytochrome b and cy tochrome c oxidase subunit II may underlie an episode of coadaptive evolution of these two proteins in the mitochondria of simian primates.
Pathways of lysozyme evolution inferred from the sequences of cytochrome b in birds
TLDR
A rapid but ancient radiation among the Galliformes such that the majority of cytochrome b sequence differences among taxa have accumulated on the terminal branches of the reconstructed phylogenetic trees.
The complete mitochondrial DNA (mtDNA) of the donkey and mtDNA comparisons among four closely related mammalian species-pairs
TLDR
The mtDNA differences between the donkey and the horse suggest that the evolutionary separation of the two species occurred =9 million years ago and the relative evolutionary rate of individual peptide-coding genes varies among different species-pairs and modes of comparison.
Comparative evolution of the mitochondrial cytochrome b gene and nuclear beta-fibrinogen intron 7 in woodpeckers.
TLDR
This study sequenced intron 7 of the beta-fibrinogen gene and compared the phylogenetic signal and nucleotide substitution properties of this DNA sequence with that of mitochondrial-encoded cytochrome b from a previous study, suggesting that introns will be useful for phylogenetic studies of recently evolved groups.
Evolutionary analysis of cytochrome b sequences in some perciformes: Evidence for a slower rate of evolution than in mammals
TLDR
Quantitative evolutionary analysis, carried out by using a markovian stochastic model, clarifies some phylogenetic relationships within the Perciformes order, particularly in the Scombridae family, and between Percirds, Gadiformes, Cypriniforms, and Acipenseriformes.
