title: Structure of mitochondrial DNA control region of Fenneropenaeus chinensis and phylogenetic relationship among different populations.
abstract: This paper deals with the structure of mitochondrial DNA control region of Fenneropenaeus chinensis. The termination-associated sequence (TAS), cTAS, CSB-D-CSB-F, and CSB-1 are detected in the species. The results indicate that the structures of these parts are similar to those of most marine organisms. Two conserved regions and many stable conserved boxes are found in the extended TAS area, central sequences blocks, and conserved sequences blocks (CSBs). This is the special character of F. chinensis. All the mtDNA control region sequences do not have CSB2 and CSB3 blocks, which is quite different from most vertebrates. In addition, the complete mtDNA control region sequences are used to analyze the phylogenetic relationships of F. chinensis. The phylogenetic trees show a lack of genetic structure among populations, which is similar to many previous studies.
