The complete mitochondrial genome of natural hybridization of Anser albifrons and Anser fabalisthe (Anser albifrons × Anser fabalis)

Hybridization between birds in wild nature is an interesting phenomenon in the wild, but not common in waterfowl in the wild. In this study, we report the complete mtDNA of the natural hybridization bird between Anser albifrons and Anser fabalis. The complete mtDNA of the hybridization is 16,740 bp...

Description
Summary:Hybridization between birds in wild nature is an interesting phenomenon in the wild, but not common in waterfowl in the wild. In this study, we report the complete mtDNA of the natural hybridization bird between Anser albifrons and Anser fabalis. The complete mtDNA of the hybridization is 16,740 bp in length, contains the typical set of 37 genes, including 13 PCGs, two rRNAs, 22 tRNAs, and a 1177 bp CR. In the 13 PCGs, ATG is generally as the start codon, TAA is the most frequent stop codon, one of three, TAA, TAG, and T-, commonly observed. All tRNAs can be folded into canonical cloverleaf secondary structures except for tRNASer (AGY) and tRNALeu (CUN) missing the “DHU” arm. The new mtDNA sequence contains 12S rRNA and 16S rRNA of rRNAs, separated with tRNAval. The CR is 1177 bp in length, located between tRNAGlu and tRNAPhe. Our phylogenetic trees suggest the hybridization has a close genetic relationship among Anser species.
