Abstract. A phylogenetic tree for major lineages of iguanian lizards is estimated from 1,488 aligned base positions (858 informative) of newly reported mitochondrial DNA sequences representing coding regions for eight tRNAs, ND2, and portions of ND1 and COI. Two well-supported groups are defined, the Acrodonta and the Iguanidae (sensu lato). This phylogenetic hypothesis is used to investigate evolutionary shifts in mitochondrial gene order, origin for light-strand replication, and secondary… 

Evolution and phylogenetic information content of mitochondrial genomic structural features illustrated with acrodont lizards.

DNA sequences from 195 squamate reptiles indicate that mitochondrial gene order is the most reliable phylogenetic character establishing monophyly of acrodont lizards and of the snake families

Molecular phylogenetics and mitochondrial genomic evolution in the chamaeleonidae (Reptilia, Squamata).

Newly reported genomic rearrangements and duplications support the hypothesis that mitochondrial gene order and content are destabilized by phylogenetic loss of a functional origin for light-strand replication between the genes encoding tRNA(Asn) and t RNA(Cys).

Mitochondrial genomes of acrodont lizards: timing of gene rearrangements and phylogenetic and biogeographic implications

The molecular data favored Gondwanan origin of Acrodonta, vicariant divergence of Agamidae and Chamaeleonidae in the drifting India-Madagascar landmass, and migration of the Agamids to Eurasia with the Indian subcontinent, although Laurasian origin ofAcrodontA was not strictly ruled out.


P phylogenetic analyses of 42 new partial mitochondrial-DNA sequences in combination with 28 previously published sequences representing all eight major groups of the lizard clade Iguanidae provide statistical support for monophyly of iguanid clades Corytophaninee, Crotaphytinae, Hoplocercinae; and Polychrotinae and Tropidurinae.

Evidence of two deeply divergent co-existing mitochondrial genomes in the Tuatara reveals an extremely complex genomic organization

Two deeply divergent co-existing mt-genomes in a vertebrate through genomic sequencing of the Tuatara (Sphenodon punctatus), the sole-representative of an ancient reptilian Order may confer an adaptive advantage for an unusually cold-tolerant reptile.

Structure and comparative analysis of the mitochondrial genomes of Liolaemus lizards with different modes of reproduction and ploidy levels

A comparative analysis of the structure and organization of the complete mitochondrial genomes of three differently related species of Liolaemus and with different reproductive strategies and ploidy levels revealed variations at the stop codons of the protein coding genes and the structure of the tRNAs among species.

Phylogenetic Relationships and Tempo of Early Diversification in Anolis Lizards

The results suggest that rapid diversi- �cation early in the evolutionary history of anoles explains why numerous researchers have had difficulty reconstructing well-supported dichotomous phylogenetic trees for anoles.

in the Chamaeleonidae (Reptilia, Squamata)

Newly reported genomic rearrangements and duplications support the hypothesis that mitochondrial gene order and content are destabilized by phylogenetic loss of a functional origin for light-strand replication between the genes encoding tRNA and tRNA.

A molecular phylogenetic analysis of diversification in Amazonian Anolis lizards

Phylogenetic analyses using maximum parsimony and maximum likelihood reject the hypothesis that Amazonian anoles form a monophyletic group excluding Central American and Caribbean anoles, and suggest multiple faunal exchanges among these regions.

Phylogenetic relationships among Agamid lizards of the Laudakia caucasia species group: testing hypotheses of biogeographic fragmentation and an area cladogram for the Iranian Plateau.

Phylogenetic relationships within the Laudakia caucasia species group on the Iranian Plateau were investigated using 1708 aligned bases of mitochondrial DNA sequence from the genes encoding ND1 (subunit one of NADH dehydrogenase) and COI, and every branch of the phylogenetic tree is well supported.



Evolution of the WANCY region in amniote mitochondrial DNA.

Phylogenetic analyses of the inferred amino acid sequences of ND2 and COI support the sister-group relationship of birds and crocodilians and suggest that mammals are an early derived lineage within the amniotes.

Variations in mitochondrial tRNA gene organization of reptiles as phylogenetic markers.

The controversial phylogenetic relationship among the Aves, Crocodilia, and Mammalia, a sister group relationship of birds and crocodilians relative to mammals, as suggested from the common loss of the stem-and-loop structure was supported with statistical significance by molecular phylogenetic analyses using the tRNA gene sequence data.

Two novel gene orders and the role of light-strand replication in rearrangement of the vertebrate mitochondrial genome.

Two novel mitochondrial gene arrangements are identified in an agamid lizard and a ranid frog and a mechanism involving errors in light-strand replication and tandem duplication of genes is proposed for rearrangement of vertebrate mitochondrial genes, implicate gene order as a reliable phylogenetic character.

Animal mitochondrial DNA: structure and evolution.

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.

Replication slippage may cause parallel evolution in the secondary structures of mitochondrial transfer RNAs.

Two mechanisms involving replication slippage can account for the loss of the cysteine tRNA D-stem in several lepidosaurian lineages, and may represent general mechanisms by which the secondary structures of mitochondrial tRNAs are altered.

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.
