Molecular Phylogeny of Vetigastropoda Based on Mitochondrial Genes, COI and 16S rRNA

The molecular phylogeny of Vetigastropoda species have been studied based on mitochondrial genes, COI and 16S rRNA in the present work for the first time in the northern rocky coastal zones of Persian Gulf during years 2013 and 2014. After morphological identifications of species, DNA extraction, amplifying partial of cytochrome oxidase COI and 16S rRNA and sequencing procedure were done in the laboratory. In this study 9 COI and 5 16S rRNA sequencing belonging to 5 species were measured. Also, phylogeny analyses with drawing phylogeny trees of Maximum Likelihood, Maximum Parsimony and Bayesian were done using MEGA6, PAUP and BEAST softwares. The result showed that clade Vetigastropoda, include Trochidae, Chilodontidae, Turbinidae and Fissurellidae families, is not monophyletic, which is not as classic identification. So Trochidae and Chilodontidae are in seprated clade from Turbinidae and Fissurellidae clade᾽s. This showed not monophyletic relation between this two group which represented difference between classic and molecular classification.
