Abstract
We sequenced the complete mitochondrial genome of Japanese Marsh Warbler (Locustella pryeri) for the first time. The mitogenome was 17,968 bp in length, contained 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 2 putative control regions. The total base composition of the mitogenome was 29.7% for A, 24.1% for T, 31.9% for C and 14.3% for G. The complete mitogenome sequence provides useful information for phylogenetic analyses among Passeriformes and species conservation.
