Oxyurichthys is a genus of goby
that is widespread in the tropical Indo-West Pacific region. Oxyurichthys species are usually
found in estuarine and coastal marine habitats. In Southeast Asia, they
are commercial fishes and often collected by trawling to serve the
market’s demand. The mitogenome serves as a good marker for
investigating the systematics and evolution of fishes, but the
mitogenome of Oxyurichthys species
remains unknown. In this study, mitogenomes of two Oxyurichthys gobies, O. ophthalmonema and O. microlepis, were characterized
and compared. The sizes of the mitogenomes were 16,504 bp and 16,506 bp
for O. ophthalmonema and O. microlepis, respectively.
Mitogenomes of these two species were similar in gene content and
structure. Both included 37 genes and a control region. The two Oxyurichthys mitogenomes shared
similar gene features and base composition with other recorded gobies.
Typical conserved blocks (CSB-1, CSB-2, CSB-3 and CSB-D) were found in
the control region of both species. Phylogenetic analyses based on
concatenation of 13 protein-coding genes and 2 rRNAs revealed that the
two Oxyurichthys species
clustered together and were sister to species of the genera Sicydium, Sicyopterus and Stiphodon. The findings of the
present study support previous evolutionary studies of gobies using
other molecular markers.
Key words: Gobies, Mitogenome, Gene structure,
Control region, Phylogeny.
