Abstract:
In this study, the complete mitochondrial genome of Heliocidaris crassispina was determined on Illumina HiSeq platform. The genome was 15,678 bp in size and contains 22 tRNA genes, 13 protein-coding genes, 2 rRNA genes and 1 control region (96 bp). The composition of A + T in H. crassispina mtDNA was 59.11%. Except ND6 and 5 tRNAs, the others are on the H-strand. The phylogenetic relationship of 11 species of sea urchins was analyzed using the neighbour-joining method by software MEGA 7.0. H. crassispina was most closely related to Pseudocentrotus depressus.
