Abstract:
Abstract: Channidae (snakehead fish) is a family of medium-to-large freshwater carnivorous fish
and contain the genus, Channa. Here, the complete mitogenomes of two Channa fish were determined
and comparatively analyzed with the mitogenomes of 16 other Channidae fish species. The
two newly sequenced complete mitogenomes were circular DNA molecules with sizes of 16,953 bp
(Channa burmanica; OP954106) and 16,897 bp (Channa aurantimaculata; OQ134162). The mitogenomes
were composed of 37 genes and one D-loop region. Positive AT skews and negative GC skews were
found in the mitogenomes. Most protein-coding genes (PCGs) started with the conventional start
codon, ATG; however, the sequence of the stop codon was variable. There was no obvious difference
in relative synonymous codon usage among the two mitogenomes, and the two species shared a
similar number of codon usage of mitogenomic PCGs, which was also similar to the mean values
for the other 15 species of Channa. All Ka/Ks values were <1; cox1 had the lowest value, and atp8 had
the highest. All of the tRNAs were typical clover structures, except trnS1. Phylogenetic analysis
showed that C. burmanica and C. aurantimaculata shared a close relationship and that they were also
closely related to C. gachua. These findings enrich the gene database of Channidae species, clarify
the mitochondrial genome structure of the two species, and provide basic data for invasive biological
surveillance in the future.
