Abstract:
In the present study, the complete mitochondrial genome of Serranidae sp. was determined first. The entire mitochondrial genome of Serranidae sp. is 16 512 bp in length, containing 13 protein-coding genes and 2 ribosomal RNA genes (rRNA), 22 transfer RNA genes (tRNA) and 2 main non-coding regions (the control region and the origin of the light-strand replication). The gene arrangement, base composition and tRNA structures of Serranidae sp. are similar to most of the bony fishes. The central conserved sequence blocks (CSB-1, CSB-2, and CSB-3) and the core sequence (ACATATATGT) of terminal-associated sequences were recognized in the control region. Meanwhile, the conserved motif 5'-GCCGG-3' was identified in the origin of light-strand replication of Serranidae sp. Phylogenetic tree, which is constructed based on the complete mitochondrial genome sequences of Serranidae sp., shows that Serranidae sp. is clustered with the fishes of the family Pentacerotidae. We expect that the mitochondrial genome of Serranidae sp. would play a key role in phylogenetic analysis of Serranidae.
