We have cloned and sequenced over 9 kb of the mitochondrial genome from the sea star Pisaster ochraceus. Within a continuous 8.0-kb fragment are located the genes for NADH dehydrogenase subunits 1, 2, 3, and 4L (ND1, ND2, ND3, and ND4L), cytochrome oxidase subunits I, II, and III (COI, COII, and COIII), and adenosine triphosphatase subunits 6 and 8 (ATPase 6 and ATPase 8). This large fragment also contains a cluster of 13 tRNA genes between ND1 and COI as well as the genes for isoleucine tRNA between ND1 and ND2, arginine tRNA between COI and ND4L, lysine tRNA between COII and ATPase 8, and the serine (UCN) tRNA between COIII and ND3. The genes for the other five tRNAs lie outside this fragment. The gene for phenylalanine tRNA is located between cytochrome b and the 12S ribosomal genes. The genes for tRNA(glu) and tRNA(thr) are 3' to 12S ribosomal gene. The tRNAs for histidine and serine (AGN) are adjacent to each other and lie between ND4 and ND5. These data confirm the novel gene order in mitochondrial DNA (mtDNA) of sea stars and delineate additional distinctions between the sea star and other mtDNA molecules.

We have cloned and sequenced a 2.65 kb segment of the mtDNA molecule of the orthopteran insect Locusta migratoria. It harbors the genes for four mitochondrial tRNAs, for cytochrome c oxidase subunits II and III and for ATPase subunits 6 and 8. The order of the locust genes resembles that of Drosophila yakuba: in both insects the genes for COII and ATPase 8 are separated from each other by the genes encoding tRNA(lys) and tRNA(asp), but in the locust, the positions of the two tRNA genes are reversed. This leads to a different mitochondrial gene order in the two insects.

Fragments of mtDNA genes Cyt B, ATPase 6, and ATPase 8 of six cottoid fishes species of Lake Baikal (East Siberia) were amplified and sequenced. In addition mtDNAs of the same fish were subjected to restriction analysis. The data obtained were used to construct phylogenetic trees. The topology of the ATPase tree differs from those of the Res (restriction) and Cyt B trees. Clustering of species within the trees confirms the viewpoint of Taliev (1955, Baicalian Sculpins (Cottoidei)) according to which Baikalian cottoids originate from two ancestral forms. The times of branching obtained do not confirm the existing viewpoint according to which the two golomyankas (Comephorus baicalensis and Comephorus dybowskii) are pre-Baikal (Myocene) relicts: these two species may have originated 1.2-1.8 million years ago in Baikal, and they seem to represent an example of rapid morphological evolution which resulted in the formation of a new family.

We present the nucleotide sequence of a 5207-bp-long region of the mitochondrial genome of the dermatophyte Trichophyton rubrum. This represents about 1/5th of the total genome and extends a previous study. From the 5' end of the present sequence, the order of genes is as follows: the end of the ND4 gene, the gene coding for subunit 6 of ATPase, the gene coding for the small ribosomal RNA (SSU rRNA), the tyrosyl tRNA gene, the ND6 gene, the COXIII gene, the ATPase 8 subunit gene and a cluster of tRNAs genes corresponding respectively to the lysine, glutamine, asparagine, isoleucine and tryptophan isoacceptors. The interesting features of this region are its compact organisation, the presence of subunit 8 of the ATPase gene and the secondary structure of SSU rRNA which is close to that of Aspergillus nidulans. On the basis of the order of the genes, which is essentially similar to that of A. nidulans, we can also assume that the LSU rRNA subunit gene should be just upstream of this sequenced region.

To investigate the potential role of mtDNA alterations during the onset of colorectal cancer, the occurrence of mtDNA variants in colorectal adenomatous (Tubular, Tubulovillous, and Villous) polyps, were studied. High resolution endonucleases and PCR-based sequence were applied to examine mtDNA variants in the ND and ATPase genes of 64 primary tissues of colorectal adeno-polyps and their matched normal controls. Forty-two variants were observed and 57% (24/42) were not previously reported in the MITODAT reference. Fifty-eight percent of these variants were germline and homoplasmic transitions. The distribution of observed mtDNA variants includes: 31% (13/42) tubular, 52% (22/42) tubulovillous, 45% (19/42) villous, and 45% (19/42) cancer (including FAP and JVP). Notably, an unreported germline variant in the ATPase 8 gene at nucleotide position (np) G8573A was observed in tubulovillous adenomas tissues. The results suggest that some specific mtDNA variants may serve as a potential biomarker for colorectal adenomatous polyps.

The mitochondrial DNA (mtDNA) ATPase 8/6 gene has been used in phylogenetic as well as in phylogeographic studies along with other mtDNA markers. In this study, ATPase gene sequences were used to assess the genetic structuring and phylogeographic patterns in Channa striata. Out of 884 nucleotide positions generated in ATPase 8/6 genes, 76 were polymorphic. The study suggested 23 unique haplotypes from 67 individuals of nine populations collected from different riverine systems of India. The ATPase 8/6 sequence revealed highest haplotype as well as nucleotide diversities in Imphal River population and lowest diversities in Tapti River population. The pattern of genetic diversity and haplotype network indicated distinct mitochondrial lineages for Chaliyar population, whereas mismatch distribution strongly suggested a population expansion in mid pleistocene epoch (0.4 Mya) with distinct genetic structuring in C. striata. The baseline information on genetic variation and the population sub-structuring would facilitate conservation and management of this important snakehead murrel.
