Abstract
The complete mitochondrial genome of Odontobutis interrupta (Perciformes, Odontobutidae),
a species endemic to South Korea, is reported here for the first time. The O. interrupta
mitogenome is 16 802 base pairs in total length and includes 13 PCGs, small and large rRNAs, a
control region and 22 tRNAs. Nine genes are encoded on the light strand and 29 on the heavy
strand. The O. interrupta mitochondrial genome has a conserved gene order compared to four
other Odontobutis species and Micropercops swinhonis, a closely related species. The data will
provide useful molecular information for phylogenetic studies concerning Odontobutidae and
its related species.

The genus Odontobutis has a limited distribution in far-east Asia
and comprises eight species (Chae, 1999; Chen et al., 2002; Iwata
& Sakai, 2002; Kottelat, 2013). Odontobutis interrupta is
endemic to South Korea and is found mainly in rivers and
tributaries flowing to the western coast of South Korea (Chae,
1999; Jeon & Kim, 1996). Due to its distribution, O. interrupta
is of interest for evolution of the genus; however, genetic
information on the species is lacking.
A specimen of O. interrupta was collected from the
Mangyoung River in Jeollabuk-Do, South Korea. The mitochon-
drial genome was amplified using long-range PCR with two
primer sets used in a previous study (Ki et al., 2008). Then, a
489-bp sequence was obtained using a primer set designed in this
study. The total length of the complete mtDNA is 16 802 bp. The
mitogenome contains large and small rRNAs and 22 tRNA,
a control region and 13 PCGs. Most of the genes are encoded on
the heavy strand, except for ND6 and eight tRNA genes (tRNA
Gln
,
tRNA
Ala
, tRNA
Asn
, tRNA
Cys
, tRNA
Tyr
, tRNA
Ser
, tRNA
Glu
and
tRNA
Pro
).
The overall base composition of the mtDNA is 29.9% A,
29.0% C, 25.5% T and 15.7% G. All of the protein-coding gene
sequences contain the orthodox ATG start codon, except for one
gene, COI, which has GTG as the start codon. Three genes (ND1,
ND3 and ND4) end in the TAG termination codon and eight genes
(ND2, COI, ATP8, ATP6, COIII, ND4L, ND5 and ND6) contain
TAA as the stop codon. The COII gene ends in an AGA
termination codon, while the CYTB gene possesses an incomplete
stop codon and has a terminal T. The lengths of the tRNA gene
sequences vary from 66 bp to 81 bp. Most of the tRNA genes can
be folded into a typical cloverleaf secondary structure. The
mtDNA gene arrangement of O. interrupta is identical to that of
the mitochondrial genomes of four other Odontobutis species
(O. platycephala, O. potamophila, O. yaluensis and O. sinensis)
and Micropercops swinhonis, within the same family (Ki et al.,
2008; Ma et al., 2015a,b,c; Zang et al., 2014). In addition, except
for the positions of three tRNAs (tRNA
Ser
, tRNA
Leu
and tRNA
His
),
the gene arrangement of O. interrupta is identical to the
mitochondrial genome of Perccottus glenii (Chen et al., 2014)
in the same family. Conserved sequence blocks (CSB1 and CSB2)
and three highly conserved areas (C, D and F boxes) were
detected within control region.
The complete mitochondrial genomes of 35 closely related
taxa available in GenBank have been used to reconstruct the NJ
phylogenetic tree (Figure 1). The phylogenetic analyses were
performed using MEGA 6.0 (iGEM, Philadelphia, PA) (Tamura
et al., 2013). Compared with genus Perccottus and Micropercops,
genus Odontobutis is more recently differentiated within family
Odontobutidae. In addition, the phylogenetic tree present that O.
interrupta and O. potamophila are recently differentiated than
other Odontobutis species. Our data will be useful for further
phylogenetic studies of the Odontobutidae and related taxa.
Nucleotide sequence accession number: The complete mito-
chondrial genome sequence of O. interrupta has been assigned the
GenBank accession number KR364945.
