Abstract

<abstract> <title>Abstract</title> <p>The complete mitochondrial genome of <italic>Johnius belangerii</italic> has been determined for the first time in this article. It was 19, 154 base pairs in length, and is composed of 37 genes (13 protein-coding genes, 22 tRNA genes and 2 ribosomal RNA genes). Totally, 5 notable non-coding regions were observed, and a non-coding of 1091 bp was identified as control region based on its location and AT richness. An 800 bp tandem repeat sequence was identified in the fifth non-coding region. We investigated the mitochondrial gene arrangement pattern and found that that the <italic>tRNA^Val, 12SrRNA, 16SrRNA</italic> and <italic>tRNA^Phe</italic> genes of <italic>J. belangerii</italic> mitogenome were orderly placed at the beginning of heavy strand. This order is different from other croakers. Combine with the phylogenetic reconstruction and genes arrangement pattern of <italic>J. belangerii</italic> mitochondrial genome, we consider <italic>J. belangerii</italic> is the most ancient genus within family Sciaenidae.</p> </abstract>
