ABSTRACT
Chilodonella hexasticha is a harmful parasitic ciliate that can cause severe damage to fish and high mortalities worldwide. Its congeneric species, C. uncinata, is a facultative parasite that not only can be free-living but also can parasitize on fish gills and fins. In this study, single-cell transcriptomes of these two species were assembled and characterized. Numerous enzymes related to energy metabolism and parasitic adaption were identified through annotation in the Non-Redundant (NR), Clusters of Orthologous Genes (COG), Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases. The expression of isocitrate dehydrogenase (IDH), cytochrome c oxidase subunit 1 (Cox1) and ATP synthase F1, delta subunit (ATP5D) was up-regulated in C. hexasticha compared with C. uncinata. The oxidative phosphorylation process was also enriched in C. hexasticha. The main mitochondrial metabolic pathways in C. hexasticha were depicted and enzymes related to energy metabolism pathways were compared between these two species. More importantly, mitochondrial division inhibitor 1 (mdivi-1) proved to be very effective in killing both C. hexasticha and C. uncinata, which could be a novel drug for Chilodonellosis control. This study can help us better understand the energy metabolisms of C. hexasticha and C. uncinata and provide new insight into novel targets for chilodonellosis control. Meanwhile, the transcriptome data can also facilitate genomic studies of these two species in the future.
