Complete mitochondrial genome of Henricia pachyderma (Asteroidea, Spinulosida, Echinasteridae) and phylogenetic analysis

Abstract

Next-generation sequencing was used to obtain the complete mitogenome of Henricia pachyderma (Hayashi, 1940). The mitogenome form was found to be a circular molecule 16,192 bp long with a 57.1% AT bias. Gene arrangement and composition of H. pachyderma were exactly the same as those of previously reported mitogenomes from other species of the family Echinasteridae, including H. leviuscula and Echinaster (Othilia) brasiliensis. Phylogenetic analysis with maximum likelihood and Bayesian inference revealed that H. pachyderma formed a monophyletic clade with H. leviuscula and E. (O.) brasiliensis belonging the same taxon, family Echinasteridae.
