In this study, 16 sets of primers were used to amplify contiguous, overlapping segments of the complete mitochondrial DNA (mtDNA) ofDanio chrysotaenitusin order to characterize and compare their mitochondrial genomes. The total length of the mitochondrial genome is 16,608 bp and deposited in the GenBank with accession numbers KP407138. The organization of the mitochondrial genomes was similar to those reported from other Mountain carp fishes mitochondrial genomes containing 37 genes (13 protein-coding genes, 2 ribosomal RNA, and 22 transfer RNAs) and a major non-coding control region (D-loop region). Most genes were encoded on the H-strand, except for the ND6 and 8 tRNA genes, encoding on the L-strand. The nucleotide skewness for the coding strands ofDanio chrysotaenitus(AT-skew = 0.10, GC-skew = −0.25) is biased toward T and G. The complete mitogenome may provide important date set for the study of genetic mechanism ofDanio chrysotaenitus. [ABSTRACT FROM AUTHOR]

The complete mitochondrial genome ofParasinilabeo assimilishas been determined in this study. The gene composition, arrangement and transcriptional orientation inP. assimilismitogenome were identical to most vertebrates. The complete mitogenome ofP. assimiliswas 16,602 bp in size with 13 protein coding genes, 22 tRNA genes and a control region. Two start codon patterns and three stop codon patterns were found in protein-coding genes. Only the tRNA-Ser2 could not fold into a typical clover-leaf secondary structure due to the lack of the dihydrouridine arm. Sequence alignment results suggest that the complete mitogenome ofP. assimilisis an efficient tool to study molecular phylogenetics, biogeography and adaptive evolution of this lineage.

The complete mitochondrial genome ofVanmanenia pingchowensiswas determined in this study. The gene composition, arrangement and transcriptional orientation inV. pingchowensismitogenome were identical to most vertebrates. The complete mitogenome ofV. pingchowensiswas 15,560 bp in size with 13 protein coding genes, 22 tRNA genes, and a control region. Two start codon patterns and three stop codon patterns were found in protein-coding genes. Only the tRNA-Ser2 could not fold into a typical clover-leaf secondary structure for lacking the dihydrouridine arm. Sequences alignment results suggest that the complete mitogenome ofV. pingchowensisis an efficient tool to study molecular phylogenetics, biogeography and adaptive evolution of this lineage.
