چکیده
The green tiger prawn, Penaeus semisulcatus is one of the most important members of the family Penaeidae in the Persian Gulf. Based on the morphological characteristics, two groups, including P. semisulcatus and its subspecies viz. P. s. persicus are recognized. This study was conducted to investigate the genetic distance between P. semisulcatus and P. s. persicus by analyzing partial sequence of 5.8S rRNA. Another objective of this study is to evaluate the ability of 5.8S rRNA to identify the species of Decapoda. The results indicated that the 5.8S rRNA gene of both P. semisulcatus and P. s. persicus were exactly identical, and sequence variation was not observed. The results also indicated that 5.8S rRNA sequences between species of the same genus of analysed species of Decapoda are conserved, and no genetic distance was observed in species level. The low evolutionary rate and efficient conservation of the 5.8S rRNA can be attributed to its role in the translation process.
