The complete mitochondrial genome sequence of Neovison vison (Carnivora: Mustelidae)

The phylogenetic and taxonomic position of the American mink Neovison vison have long been unclear. In this paper, the complete mitogenome of N. vison was sequenced and characterized. The total length was 16,594 bp and typically consists of 37 genes, including 13 protein-coding genes, 2 rRNAs, 22 tRNA, a large control region (CR) and a light-strand replication origin (OL). Gene contents, locations, and arrangements were identical to those of typical vertebrate. The overall base composition is 33.6%, 25.4%, 27.8% and 13.3% for A, C, T and G, respectively, with a moderate bias on AT content (61.4%). This result is expected to provide useful molecular data and contribute to further taxonomic and phylogenetic studies of Mustelidae and Carnivora.

Phylogenetic studies of Anas clypeata (Anatidae: Anas) based on complete mitochondrial DNA sequences

Northern shoveler (Anas clypeata) is a middle-sized duck living in an extremely geographical range in northern hemisphere. Here, the complete mitochondrial genome of A. clypeata (16 599 bp in length) has been analyzed for building the database. Similar to the typical mtDNA of vertebrates, it contained 37 genes (13 protein-coding genes, 2 rRNA genes and 22 tRNA genes) and a non-coding region (D-loop). Overall base composition of the complete mitochondrial DNA is A (29.4%), G (15.7%), C (32.5%) and T (22.4%), the percentage of A and T (51.8%) is slightly higher than G and C (48.2%). All the genes in A. clypeata were distributed on the H-strand, except for the ND6 subunit gene and 9 tRNA genes which were encoded on the L-strand. The phylogenetic relationships of 12 Anatidae species were reconstructed based on the complete mtDNA sequences using the Bayesian inference method.

Mitochondrial genome of the Anas crecca (Anatidae: Anas)

Mitochondrial DNA plays an important role in living organisms, and has been used as a powerful molecular marker in various evolutionary studies. In this study, we determined the complete mitochondrial genome of Anas crecca (16,601 bp in length). Similar to the typical mtDNA of vertebrates, it contained 37 genes (13 protein-coding genes, 2 rRNA genes and 22 tRNA genes) and a non-coding region (D-loop). Overall base composition of the complete mitochondrial DNA was 29.05% A, 22.35% T, 32.64% C and 15.96% G.

Complete mitochondrial genome of the Korean reeves's turtle Mauremys reevesii (Reptilia, Testudines, Geoemydidae)

The mitochondrial genome of Korean reeves's turtle Mauremys reevesii (Reptilia, Testudines, Geoemydidae) was studied. The complete mitochondrial genome sequence of M. reevesii was 16,784 bp in length and its gene arrangement pattern, gene content and gene organization is identical to those of geoemydids. The control region (CR) was located between the tRNA(Pro) and tRNA(Phe) genes and is 1253 bp in length. The typical conserved domains such as TAS and CSB-F, and CSB1, CSB2 and CSB3 were identified in the CR of geoemydids.

Determination and analysis of complete mitochondrial genome sequence of mallard (Anas platyrhychos)

The complete mitochondrial genome (mtDNA) of mallard (Anas platyrhychos) was determined by long and accurate polymerase chain reaction and with primer walking sequence method. The entire genome was 16,606 bp in length. Similar to the typical mtDNA of vertebrates, it contained 37 genes (13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes) and a non-coding region (D-loop). The characteristics of the mitochondrial genome were analyzed and discussed in detail.

Mitochondrial genome of the cockscomb pearl mussel Cristaria plicata (Bivalvia, Unionoida, Unionidae)

The complete mitochondrial genome sequence of the cockscomb pearl mussel Cristaria plicata, which is an endangered species in South Korea, was sequenced. The circle genome (15,708 bp in size) consists of 13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes. There were 26 noncoding regions (NCs) found throughout the mitogenome of C. plicata, ranging in size from 2 to 327 bp, and the two largest NC regions, NC286 and NC326, were found between ND5 and tRNA(Gln) (286 bp) and between tRNA(Glu) and ND2 (326 bp), respectively. The 13 mitochondrial protein-coding genes of a female individual of C. plicata collected from Korea (15,708 bp) were compared to those of the Chinese individual (15,712 bp) published before. The result showed that ND3 is the most conserved with 100% nucleotide similarity, and each of the other protein-coding genes has ca. 99%, respectively. The two largest NCs among 26 NCs have totally 98% nucleotide similarity between Korean and Chinese ones.
