Abstract

The complete mitochondrial genome (mitogenome) of the jewel beetle, Coraebus cavifrons, was sequenced and described in the present study. The mitogenome of Coraebus cavifrons is a typical circular DNA molecule of 15,686 bp. All of the 37 mitochondrial genes (13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes) were annotated and a putative control region with 1135 bp in length was found between tRNA ^Ile and srRNA. Protein-coding genes all initiate with ATN codons except for COII uses GTG. Most of the protein-coding genes use TAA or TAG as the stop codon, but COII, COIII, and ND5 terminate with a single T. All tRNAs have the clover-leaf structure except for tRNA ^Ser(AGN) and the length of them range from 60 to 71 bp. Genome organization and nucleotide composition of the mitogenome were also noted. Our phylogenetic analysis of Elateriformia supported the monophyly of Buprestoidea and the sister relationship between Buprestoidea and (Byrrhoidea + Elateroidea).

Insect mitochondrial genomics: implications for evolution and phylogeny.

Stephen Cameron (2014)

The mitochondrial (mt) genome is, to date, the most extensively studied genomic system in insects, outnumbering nuclear genomes tenfold and representing all orders versus very few. Phylogenomic analysis methods have been tested extensively, identifying compositional bias and rate variation, both within and between lineages, as the principal issues confronting accurate analyses. Major studies at both inter- and intraordinal levels have contributed to our understanding of phylogenetic relationships within many groups. Genome rearrangements are an additional data type for defining relationships, with rearrangement synapomorphies identified across multiple orders and at many different taxonomic levels. Hymenoptera and Psocodea have greatly elevated rates of rearrangement offering both opportunities and pitfalls for identifying rearrangement synapomorphies in each group. Finally, insects are model systems for studying aberrant mt genomes, including truncated tRNAs and multichromosomal genomes. Greater integration of nuclear and mt genomic studies is necessary to further our understanding of insect genomic evolution.

The mitochondrial DNA molecular of Drosophila yakuba: nucleotide sequence, gene organization, and genetic code.

D. R. Wolstenholme, D O Clary (1984)

The sequence of the 16,019 nucleotide-pair mitochondrial DNA (mtDNA) molecule of Drosophila yakuba is presented. This molecule contains the genes for two rRNAs, 22 tRNAs, six identified proteins [cytochrome b, cytochrome c oxidase subunits I, II, and III (COI-III), and ATPase subunits 6 and 8] and seven presumptive proteins (URF1-6 and URF4L). Replication originates within a region of 1077 nucleotides that is 92.8% A + T and lacks any open reading frame larger than 123 nucleotides. An equivalent to the sequence found in all mammalian mtCDNAs that is associated with initiation of second-strand DNA synthesis is not present in D. yakuba mtDNA. Introns are absent from D. yakuba mitochondrial genes and there are few (0-31) intergenic nucleotides. The genes found in D. yakuba and mammalian mtDNAs are the same, but there are differences in their arrangement and in the relative proportions of the complementary strands of the molecule that serve as templates for transcription. Although the D. yakuba small and large mitochondrial rRNA genes are exceptionally low in G and C and are shorter than any other metazoan rRNA genes reported, they can be folded into secondary structures remarkably similar to the secondary structures proposed for mammalian mitochondrial rRNAs. D. yakuba mitochondrial tRNA genes, like their mammalian counterparts, are more variable in sequence than nonorganelle tRNAs. In mitochondrial protein genes ATG, ATT, ATA, and in one case (COI) ATAA appear to be used as translation initiation codons. The only termination codon found in these genes is TAA. In the D. yakuba mitochondrial genetic code, AGA, ATA, and TGA specify serine, isoleucine, and tryptophan, respectively. Fifty-nine types of sense condon are used in the D. yakuba mitochondrial protein genes, but 93.8% of all codons end in A or T. Codon-anticodon interactions may include both G-A and C-A pairing in the wobble position. Evidence is summarized that supports the hypothesis that A and T nucleotides are favored at all locations in the D. yakuba mtDNA molecule where these nucleotides are compatible with function.
