Abstract
The complete mitochondrial genome of Mekongiella kingdoni, which was collected from the Tibetan Plateau, is determined here. It is 15,932 bp in length and contains 73.1% AT. All M. kingdoni protein-coding sequences except for the cox1 start with a typical ATN codon. Instead, CCG, which is a rare but possible initiation codon, is located at the initiation context of cox1. The usual termination codons (TAA and TAG) and incomplete stop codons (TA or T) are found from 13 PCGs. All tRNA genes can be folded into the typical cloverleaf secondary structure, except trnS(AGN) due to the lacking of dihydrouridine arm. The sizes of the large and small ribosomal RNA genes are 1313 and 837 bp, respectively. The AT content of the A + T-rich region is 78.4%.
