A distinct mitogenome of peanut worm Sipunculus nudus (Sipuncula, Sipunculidae) from Beibu Gulf

Abstract

Peanut worm, Sipunculus nudus is a cosmopolitan species found in inter-tidal sands. In this article, based on the samples collected from the Beibu Gulf, China, a mitochondrial DNA sequence by Illumina high throughput sequencing, was carried out on muscle and determined the complete mitogenome. This mitogenome of peanut worm is 15,331 base pairs in length (Accession number: MN481531) and comprises of 37 genes as in the typical mitochondrial gene arrangement of Sipunculus. Moreover, the phylogenetic analysis shows that our sample is a novel type in China and has a distantly genetic relationship with the known populations in South China Sea. This mitogenome will serve as the foundation for the molecular genetic studies of peanut worm.
