Chinese sleeper ( Perccottus glenii) belongs to the largest vertebrate order, Perciformes. In this study, the complete mitochondrial genome of P. glenii was determined to be 16,487 bp in length, including 13 protein-coding genes, 22 transfer RNA genes and 2 ribosomal RNA genes. We also analysed the sequence structure of non-coding control region. Comparing the mitochondrial genome of P. glenii with its congener Rhyacichthys aspro showed sequence similarity and the identical gene arrangement. The complete mitochondrial genome of Chinese sleeper provides the basis for the studies in Perciformes evolution and conservation. [ABSTRACT FROM AUTHOR]

The kissing gourami (Helostoma temminkii) belongs to the Labyrinth fishes (Perciformes: Anabantoidei), which exhibits a wide variety of behavioral traits. In this study the complete mitogenome of H. temminkii was determined to be 16,740 bp in length. It contains 13 protein-coding genes, 22 transfer RNA genes and 2 ribosomal RNA genes. The sequence structure of non-coding control region was also analyzed. Comparing the mitochondrial genome of H. temminkii with its closely related species Colisa lalia showed the similarity of 78%. The complete mitochondrial genome of H. temminkii provides resource for phylogenetic analysis on Anabantoidei. [ABSTRACT FROM AUTHOR]
