Complete mitochondrial genome sequence of Hemiculter bleekeri

Abstract

In our research, the complete mitochondrial DNA (mtDNA) of Hemiculter bleekeri was obtained from the dorsal myotome of the fish. The total length of the mitochondrial genome is 16,617 bp and deposited in GenBank with accession number KU198332. The gene arrangement was similar to other bony fishes, which contained 37 genes (13 protein-coding genes, 2 ribosomal RNA and 22 transfer RNAs) and a major non-coding control region. The mtDNA may provide some important genetic background information of this valuable fish. The G contents was relatively low in the total mtDNA with the GCskewthinsp;= −0.22. The negative GC-skew ranging from −0.51(ATP8) to −0.19(CO1), and the more positive AT-skew varying from −0.26(ATP8) to −0.03(CO1). The phylogenetic analysis demonstrated that H. Bleekeri was clustered together with Hemiculter leucisculus, which could be a sister species.
