Abstract:
The freshwater sleeper, Sineleotris saccharae Herre, 1940 is a member of the Odontobutiae family, widely distributed in southern China. In the present study, we determined the complete mitochondrial genome of S. saccharae for the first time and analyzed its evolutionary relationship. The complete mitochondrial genome of S. saccharae was 16,487 bp long, and had 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), 2 ribosomal RNA (rRNAs) and a control region (CR). The mitogenome of S. saccharae shared the same gene organization and orientation as other teleosts. According to phylogenetic research, S. saccharae was sister to S. chalmersi with high support value, providing the monophyly of the genus Sineleotris. These results will be helpful for understanding the systematics of the odontobutids.
