ABSTRACT
BACKGROUND:
The Muricidae family in the Class Gastropoda comprises numerous species with a vast range of morphological features and a worldwide presence. The phylogeny of the Muricidae has been analyzed in previous studies; however, the evolutionary relationships among the main branches of the Muricidae remain unknown. METHODS ANDRESULTS:
In the present study, the mitochondrial genome of Mancinella alouina was sequenced. The mitochondrial genome was found to be 16,671 bp in length and made up of 37 genes (13 protein-coding genes, 22 transfer RNA and 2 ribosomal RNA genes). The genome has an A-T-rich region (66.5% A + T content) and all of the PCGs use the ATN start codon and the TAG or TAA stop codons. The mitochondrial gene arrangement of Mancinella alouina is similar to that of other Muricidae, except for Ocinebrellus inornatus and Ceratostoma burnetti. On the basis of a flexible molecular clock model, time-calibrated phylogenetic results indicate that the genus Mancinella diverged roughly 18.09 Mya, and that the family Muricidae emerged in the Late Cretaceous.CONCLUSIONS:
This study reveals the structural and sequence information features of the mitochondrial genome of Mancinella alouina. This study provides evidence for the relationships within the family Muricidae at the molecular level, and infer the divergence time. The results of phylogenetic analyses strongly support the current classification.Palabras clave
