Four complete mitochondrial genomes of Saurogobio fishes (Cypriniformes: Gobionidae)

摘要

In this study, we determined complete mitochondrial genomes of Saurogobio gracilicaudatus , S. xiangjiangensis , S. gymnocheilus , and S. lissilabris so that these data could contribute to reconstruct interspecific phylogenetic relationships within the genus Saurogobio . The four mitochondrial genomes showed A?+?T bias (55.2–57.0%) of base compositions with the length from 16,594 to 16,608?bp. Phylogenetic relationships among Saurogobio fishes and their close relatives showed that the genus Saurogobio was a monophyletic group and it could be divided into two major groups.
