The tapestry of the Middle East: diversity and phylogeny of Dactylogyrus reveal the evolutionary pattern of parasites and their cyprinoid fish hosts

Original language description

Several recent studies explored the diversity and phylogeny of host-specific Dactylogyrus (Monogenea), gill parasites of cypri¬noid fish, within the peri-Mediterranean region. However, the diversity and phylogeny of Dactylogyrus species in the Middle East are neglected. To reveal historical dispersion of cyprinoid fish through the phylogenetic relationships of their associated Dactylogyrus species, we aimed to reconstruct the phylogeny of Dactylogyrus spp. including the species collected in the Middle East. Several field trips in Iran, Iraq, and Turkey were conduct¬ed, and the gills of 89 cyprinoid species were examined for the presence of Dactylogyrus species. Seventy-two Dactylogyrus species were identified. Dactylogyrus vistulae, with 24 host species, had the widest host range in the Middle East. Concerning Dactylogyrus diversity at individual host species, Squalius spp. harbored the most Dactylogyrus species on them. Our sampling revealed over¬all sixteen potentially new Dactylogyrus species for science. The partial fragments of 18S rDNA and 28S rDNA, and the complete ITS1 region were used for phylogenetic reconstruction. Several Dactylogyrus species exhibited high genetic intraspecific variabil¬ities. Phylogenetic reconstruction using Middle Eastern Dactylo-gyrus species and those corresponding to different geographical regions retrieved from GenBank revealed eight major clades. Middle Eastern species were present in five clades alongside Eu¬ropean, North African, and East Asian species, thus confirming the significant role of Middle East in Dactylogyrus diversification. Mapping morphological characters of haptor onto the phylogeny revealed the evolution of parasite haptor adaptation to their host historical dispersal route.
