Abstract
In this study, the complete mitochondrial genome of Salmacis sphaeroides variegate was determined on Illumina HiSeq platform. The genome was 15,770 bp in size and contains 22 tRNA genes, 13 protein-coding genes, 2 rRNA genes, and 1 control region (180 bp). The composition of A + T in S. sphaeroides mtDNA was 61.90%. Except ND6 and 6 tRNAs, the others are on the H-strand. The phylogenetic relationships of 11 species of sea urchins were analyzed using the neighbor-joining method using software MEGA 7.0. S. sphaeroides was most closely related to Temnopleurus hardwickii.
Figure 1. Consensus neighbor-joining tree based on the complete mitochondrial sequence of S. sphaeroides and other 10 species of sea urchins. The phylogenetic tree was constructed using MEGA 5.0 software by the neighbor-joining method. The numbers at the tree nodes indicate the percentage of bootstrapping after 1000 replicates.
