Identifies the complete mitochondrial genome and relationships of Chrysaora chinensis, suggesting new insights into jellyfish taxonomy.
The scyphozoan jellyfish Chrysaora chinensis has been frequently observed in the coastal waters of Fangchenggang, China, in recent years. This study assembled and analyzed the first complete mitochondrial genome (mitogenome) of C. chinensis from next-generation sequencing data. The mitogenome was 16,783 bp in length, exhibited an overall AT content of 69%, and encoded 13 typical protein-coding genes (PCGs), 2 ribosomal RNA (rRNA) genes (rrnS and rrnL), 2 transfer RNA (tRNA) genes (trnW-tca and trnM-cat), and an additional open reading frame (ORF), dpo. The mitochondrial gene order was largely consistent with that of previously reported jellyfish species. Furthermore, phylogenetic analysis of 13 mitochondrial PCGs from 19 jellyfish species indicated that Chrysaora chinensis is closely related to Chrysaora pacifica and Chrysaora quinquecirrha. These results provided a valuable reference for clarifying the taxonomy, evolutionary relationships, and phylogeography of scyphozoan jellyfish.
