title: Complete mitogenome of the brown guitarfish Rhinobatos schlegelii (Rajiformes, Rhinobatidae).
abstract: The complete mitochondrial genome of the brown guitarfish Rhinobatos schlegelii is presented for the first time in this study. It is 16,780 bp in length, consisting 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and 1 putative control region with the typical gene order and direction of transcription in vertebrates. The overall base composition is 32.1% A, 26.3% C, 13.2% G and 28.3% T. Two start codon (GTG and ATG) and two stop codon patterns (TAG and TAA/T) were found in protein-coding genes. The 22 tRNA genes ranged from 67 (tRNA-Ser2) to 75 (tRNA-Leu1) bp in length. The origin of L-strand replication (OL) was between tRNA-Asn and tRNA-Cys genes within the WANCY region. The tRNA-Ser2 could not be fold into the typical cloverleaf secondary structure because of the replacement of its dihydrouridine arm by a simple loop. The control region was 1089 bp in length with high A + T content (64.0%).
