Phylogenetic clustering of dinoflagellate hosting-cyanobionts. A maximum Likelihood tree based on the V3–V4 regions of the cyanobacterial 16S rDNA gene was inferred using IQ-TREE under the TN + F + R2 model. Each host genus with cyanobionts (grey) is illustrated. Different colors of text and lines represent each host genus. Capital letters indicate the genetic clade of Ornithocercus mentioned in Fig. 3.
