The complete mitochondrial genome of Poraniopsis inflata (Asteroidea: Valvatida: Poraniidae) from Dokdo Island, Korea

Abstract

This study presents the complete mitochondrial genome sequence of Poraniopsis inflata, providing valuable information on its genetic and taxonomic studies. Through next-generation sequencing, we successfully obtained the complete mitogenome of P. inflata, spanning a length of 16,322 bp. This genome structure encompasses 13 protein-coding genes (PCGs), 22 transfer RNA genes, and two ribosomal RNA genes. The phylogenetic analysis, based on a dataset of 13 PCG sequences, illuminated the phylogenetic relationships of P. inflata with other species of class Asteroidea and a species of echinoderm classes. The maximum likelihood phylogenetic tree showed that P. inflata closely clustered with Linckia laevigata. By revealing its mitochondrial genome and positioning it within the Asteroidea lineage, this study provides insights into the phylogenetic context of P. inflata.
