Figure 1.
Phylogenetic tree of 10 species in Holothuroidea. The complete mitogenomes is downloaded from GenBank and the phylogenic tree is constructed by maximum-likelihood method with 100 bootstrap replicates. The bootstrap values were labeled at each branch nodes. The gene's accession number for tree construction is listed as follows: Stichopus horrens (NC_014454), Parastichopus nigripunctatus (NC_013432), Apostichopus japonicus (NC_012616), Parastichopus californicus (NC_026727), Parastichopus parvimensis (NC_029699), Benthodytes marianensis (NC_040968), Holothuria forskali (NC_013884), Holothuria scabra (NC_027086), and Cucumaria miniata (NC_005929).
