The complete mitochondrial genome of Plumarella spinosa (Octocorallia: Calcaxonia: Primnoidae) from South Korea

Abstract

Plumarella spinosa (Anthozoa: Octocorallia: Primnoidae) is an endangered marine soft coral species discovered on a 50–100 m deep reefs in South Korea. We analyzed the mitochondrial genome sequence of this species. The genome size was 19,037 bp in length consisting of 14 protein coding genes (PCGs), two rRNA genes and a tRNA gene. Our phylogenetic analysis for this species with 33 Octocorallia species reconstructed based on the nucleotide sequences of 14 PCGs showed that P. spinosa was placed as a sister to Narella hawainensis and Primnoidae formed a monophyletic group.
