In this study, we cloned and sequenced the complete mitochondrial genome (mitogenome) ofMacrognathus aculeatus.The genome is a circular molecule of 16,537 bp in length and consists of 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes and 2 main non-coding regions (the control region and the origin of the light strand replication). The overall base composition ofM. aculeatusis 30.03% for A, 26.46% for T, 28.72% for C and 14.79% for G, with a slight A + T bias of 56.49%. It has the typical vertebrate mitochondrial gene arrangement. [ABSTRACT FROM PUBLISHER]

The mitochondrial genome of the Chinese bitterling Rhodeus sinesis is a circular molecule of 16,677 bp in length, containing 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and two main non-coding regions (the control region and the origin of the light strand replication). The gene composition and order of which were similar to most other vertebrates. All protein-coding genes are initiated with ATG except for COX 1, which begin with GTG instead. However, the termination codons of 13 protein-coding genes are varied with TAA, TA, T or TAG. The molecular data we presented here could provide useful information for the studies on species identification, evolutionary relationships and population genetics of the Acheilognathinae.

In this study, we cloned and sequenced the complete mitochondrial genome of Odontobutis potamophila. The genome was found to be 16,932 bp in size with a mostly conserved structural organization when compared with that of other teleost fish. It contained 37 genes (13 protein-coding genes, 22 transfer RNA genes, and 2 ribosomal RNA genes) and 2 main non-coding regions (the control region and the origin of the light strand replication). Rearrangements of tRNAs (tRNA-Ser, tRNA-Leu, tRNA-His) and three additional longer non-coding regions (43 bp, 336 bp and 76 bp, respectively) were present between the ND4 and ND5 genes. Within the control region, typical conserved domains, such as the termination-associated sequence, central and conserved sequence blocks domains were identified. This mitogenome sequence data would contribute to better understanding population genetics and phylogenetic analysis of the Odontobutidae. [ABSTRACT FROM AUTHOR]

In this study, we present the complete mitochondrial gene for the freshwater goby Rhinogobius giurinus. The genome is a circular molecule of 16,520 bp in length and consists of 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes and 2 main non-coding regions (the control region and the origin of the light strand replication). The overall base composition of R. giurinus is 26.08% for T, 29.56% for C, 27.73% for A and 16.63% for G, with a slight A + T bias of 53.81%. It has the typical vertebrate mitochondrial gene arrangement. [ABSTRACT FROM AUTHOR]

Acheilognathus macropterusbelongs to the family Acheilognathinae. In the present study, we obtain the complete mitochondrial genome of the Chinese bitterlingA. macropterusby PCR amplification and DNA sequencing. It is a circular double-stranded DNA molecule of 16,773 bp in length, containing 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and two main non-coding regions (the control region and the origin of the light strand replication). The gene composition and order of which are similar to most other vertebrates. Compared withAcanthorhodeus macropterus, they share 98.90% nucleotide sequences similarity, and the biggest nucleotide sequence discrepancy between homologous genes are observed inND5gene. The molecular data we presented here could provide useful information for the studies on species identification, evolutionary relationships and population genetics of the Acheilognathinae.

For understanding the phylogenetic position of Micropercops swinhonis within the family Odontobutidae, the complete nucleotide sequence of M. swinhonis mitochondrial genome was firstly determined. The genome is 16,493 bp in length, and consists of 37 genes (13 protein-coding genes, 22 transfer RNA genes and 2 ribosomal RNA genes) and 2 main noncoding regions (the control region and the origin of the light strand replication). The gene composition and order of which were similar to most other vertebrates. Within the control region, typical conserved domains, such as the termination-associated sequence, central and conserved sequence blocks domains were identified. [ABSTRACT FROM AUTHOR]
