Abstract
The complete circular mitochondrial genome (mitogenome) of Bryodema miramae is 15,919 bp in length, containing 37 typical genes and 1 non-coding AT-rich region. The AT content of the AT-rich region is 84.7%. All protein-coding genes (PCGs) start with standard ATN initiation codon and end with complete termination codons TAG or TAA except for cox1 gene using an incomplete stop codon T. tRNA genes are predicted with a characteristic cloverleaf secondary structure except for trnSAGN, whose dihydrouridine (DHU) arm is replaced by a simple loop. The lengths of the large and small ribosomal RNA genes are 1319 and 836 bp, respectively. Phylogenetic analysis found: (i) Bryodema miramae has a close relationship with Bryodema luctuosum luctuosum, but with low credibility, the bootstrap value was under 50% and (ii) the Bryodema clade forms a sister group with another clade containing Orinhippus tibetanus and Pacris xizangensis.
