ABSTRACT
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.

The mitochondrial genome of Aythya ferina (Anatidae: Aythya) is a circular molecule of 16,616 bp in length, containing 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and one control region (D-loop). Overall base composition of the complete mitochondrial DNA was 29.42% A, 22.19% T, 32.83% C and 15.56% G. All the genes in A. ferina were distributed on the H-strand, except for the ND6 subunit gene and eight tRNA genes which were encoded on the L-strand.

Aythya fuligula belongs to the genus of Aythya (Anseriformes, Anatidae), which only has 12 species worldwide. The complete mitochondrial genome sequence of A. fuligula was implemented. A circular molecule of 16,616 bp in length, containing 13 protein-coding genes, 2 rRNA genes, 22 tRNAs and a non-coding AT-rich region. Its gene arrangement patterns were identical to the most other species of Anseriformes.

Aix galericula has very wide geographical range in eastern Asia. Here, the complete mitochondrial genome of A. galericula (16,605 bp in length) 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). All the genes in A. galericula were distributed on the H-strand, except for the ND6 subunit gene and 10 tRNA genes which were encoded on the L-strand.

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.

The Northern Pintail (Anas acuta) is a common large duck with widely geographic distribution. In this study, the complete mitochondrial genome of A. acuta (16,599 bp in length) was 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). All the genes in A. acuta were distributed on the H-strand, except for the ND6 subunit gene and 10 tRNA genes which were encoded on the L-strand.

The Emberiza aureola (yellow-breasted bunting), Vulnerable (IUCN), is a Eurasian bird with very wide geographical range. The complete mitochondrial genome of E. aureola (16,800 bp in length) contained 37 genes (13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes) and a non-coding region (D-loop), which is similar to the typical mtDNA of vertebrates. All the protein-coding genes in E. aureola were distributed on the H-strand, except for the ND6 subunit gene and ten tRNA genes which were encoded on the L-strand.
