The mitochondrial genome of the long-billed plover, Charadrius placidus (Charadriiformes: Charadriidae).

The present study provides the first full mitochondrial genome sequence of a long-billed plover from South Korea. This mitogenome is 16,895 bp in length and consists of 13 protein-coding genes, 2 ribosomal-RNA genes, 22 transfer-RNA genes, and a non-coding control region. Overall, base composition was: A, 31.4%; C, 31.1%; G, 13.8%; and T, 23.8%. A frameshift mutation in the ND3 gene was identified and a tandem repeat (AACA) was observed in the D-loop region. The phylogenetic analysis based on concatenated coding genes indicated Charadriidae's monophyly. These results contribute to further understanding of long-billed plover phylogenetic relationships and species identification.
