Complete mitochondrial genome sequences of a deep-sea holothurian species of the genus Scotoplanes (Elasipodida: Elpidiidae)

Figures & data

Figure 1. Maximum likelihood (ML) phylogeny of 13 holothurians based on concatenated amino acid sequences of 13 protein-coding genes (3570 positions). Scotoplanes sp. is shown in bold. Also included in the analysis was the echinoid Strongylocentrotus droebachiensis as an outgroup taxon, according to relationships among the five echinoderm classes inferred from phylogenomic analysis (Telford et al. 2014). Sequences were aligned separately for each gene by using MAFFT 7.397 (Katoh and Standley 2013) with default parameters. Ambiguously aligned positions were removed by Gblocks 0.91b (Castresana 2000); the ‘Allowed gap positions’ was set to ‘With half'. ML analysis was performed in RAxML 8.2.10 (Stamatakis 2014) using the mtREV + G model. Numbers above or below branches denote bootstrap percentages (1000 replicates). DDBJ/EMBL/Genbank accession numbers are shown for published sequences.
