Complete mitochondrial genome of Sineleotris saccharae (Perciformes,
Odontobutiae) and phylogenetic analysis
The freshwater sleeper, Sineleotris saccharae, endemic to southeastern
of China belongs to the family of Odontobutiae. The composition of the
Odontobutidae is controversial due to the lack of molecular data.
Information about genetic characteristics of S. saccharae was still not
reported. 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 in length, and consisted of 13 protein-coding genes (PCGs), 22
transfer RNAs (tRNAs), 2 ribosomal RNA (rRNAs) and a control region
(CR). The gene arrangement and orientation of S. saccharae mitogenome
was identical to those of other teleosts. Phylogenetic analysis by
Maximum likelihood (ML) methods strongly supported the monophyly of
Odontobutidae containing two clades. The genus Odontobutis was sister to
the clade consisting of Perccottus and Neodontobutis. Meanwhile,
Microdous, Sineleotris and Micropercops formed another clade. These data
will be helpful for understanding the genetic information of S.
saccharae and systematics of the odontobutids.
