The complete mitochondrial genome of large odorous frog, Odorrana graminea (Amphibia: Ranidae) and phylogenetic analysis.

The mitochondrial genome of Odorrana graminea was sequenced and analyzed. The complete mitochondrial genome is 18,106 bp in length, including 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, 21 transfer RNA genes, and a control region (D-loop). All PCGs are initiated by ATN codons, except for GTG for COI and ND5. Five PCGs use a common stop codon of TAA or TAG, whereas COI terminats with AGG as stop codon; ND6 with AGA; the other six ends with an incomplete stop codon (a single stop nucleotide T). The analysis results based on Bayesian inference method provide a useful resource for the phylogenetic studies of superfamily Ranoidea.
