Abstract: | To understand the systematic status of Bahaba
taipingensis within Sciaenidae, the complete mitochondrial genome (mitogenome) sequence of Chinese bahaba has recently been determined by long PCR and primer walking methods. The complete mitochondrial genome is 16500 bp in length and contains 37 mitochondrial genes (13 protein-coding genes, 2 ribosomal RNA genes and 22 transfer RNA genes) as well as a control region (CR) as other bony fishes. Within the control region, we identified the extended termination associated sequence domain (ETAS), the central conserved sequence block domain (CSB-D, SCB-E and CSB-F) and the conserved sequence block domain (CSB-1, CSB-2 and CSB-3). Phylogenetic analyses revealed that Bahaba
taipingensis is more closely related to Pseudosciaeniae than Argyrosominae and Sciaeninae. Additionally, Bahaba
taipingensis is the sister taxon of Miichthys
miiuy, and those two are sister to Collichthys plus Larimichthys. |
