The Complete Mitochondrial Genome of Glyptothorax macromaculatus Provides a Well-Resolved Molecular Phylogeny of the Chinese Sisorid Catfishes.

ABSTRACT: Previous phylogenetic analyses of the Chinese sisorid catfishes have either been poorly resolved or have not included all the 12 sisorid genera. Here, we successfully assembled the first complete mitochondrial genome of the sisorid fish Glyptothorax macromaculatus. Based on this novel mitochondrial genome and previously published mitochondrial genomes in the Sisoridae, we generated maximum likelihood and Bayesian phylogenies. We dated our preferred topology using fossil calibration points. We also tested the protein-coding genes in the mitochondrial genomes of the glyptosternoid fishes for signals of natural selection by comparing the nucleotide substitution rate along the branch ancestral to the glyptosternoid fishes to other branches in our topology. The mitochondrial sequence str
