摘要

Background

Although the genus Pleurocorallium contains an economically valuable species, limited genetic information is available. Here, we report the complete mitochondrial genome sequence of Pleurocorallium inutile. In Japan, this species is known as damesango, meaning “useless coral”, because it has no commercial value when caught as a bycatch during precious coral harvesting. Although several species of Pleurocorallium can be distinguished morphologically, some cannot be differentiated using the limited number of characterized genetic regions, such as eight mitochondrial and elongation factor genes. P. inutile is one such species, and therefore, analyzing its complete mitochondrial genome will be useful for identifying its phylogenetic status, distinguishing it from other commercially important species, and providing insights into the evolution of octocoral mitochondrial genes.

Methods and results

The 18,822 bp mitochondrial genome of P. inutile consists of 14 protein-coding genes, two ribosomal RNA (rRNA) genes (rnL and rnS), and one tRNA gene (trnM). Consistent with previous studies, P. inutile shares the same gene arrangement as other Pleurocorallium species, while exhibiting distinct gene arrangements compared to closely related genera, such as Corallium and Hemicorallium. A phylogenetic tree based on protein-coding and rRNA genes from currently available Coralliidae species indicated that Pleurocorallium exhibited greater within-genus genetic distances than Corallium and Hemicorallium.

Conclusions

Our study clearly distinguished P. inutile from other species using published mitochondrial genomes. This sequence information will be useful for accurate biodiversity assessments and understanding octocoral mitochondrial gene evolution in the future.
