英文摘要: Myxozoa, a diverse group of morphologically simplified endoparasites, are well known fish parasites causing substantial economic losses in aquaculture. Despite active research, the phylogenetic position of Myxozoa remains ambiguous. After obtaining the genome and transcriptome data of the myxozoan Thelohanellus kitauei, we examined the phylogenetic position of Myxozoa from three different perspectives. First, phylogenomic analyses with the newly sequenced genomic data strongly supported the monophyly of Myxozoa and that Myxozoa is sister to Medusozoa within Cnidaria. Second, we detected two homologs to cnidarian-specific minicollagens in the T. kitauei genome with molecular characteristics similar to cnidarian-specific minicollagens, suggesting that the minicollagen homologs in T. kitauei may have functions similar to those in Cnidaria and that Myxozoa is Cnidaria. Additionally, phylogenetic analyses revealed that the minicollagens in myxozoans and medusozoans have a common ancestor. Third, we detected 11 of the 19 proto-mesodermal genes in the T. kitauei genome, which were also present in the cnidarian Hydra magnipapillata, indicating Myxozoa is within Cnidaria. Thus, our results robustly support Myxozoa as a derived cnidarian taxon with an affinity to Medusozoa, helping to understand the diversity of the morphology, development and life cycle of Cnidaria and its evolution.
