are diatoms Rhizarian?
The main patterns to emerge from this are that, while there are many nuclear genomes available, they are strongly biased to a few lineages, mostly animals, fungi, plants, and parasites. On the other end of the spectrum, Rhizaria (with two genomes) is the worst sampled of any supergroup.ther more enigmatic parasitic groups are also known, such as the phagomyxids, which infect diatoms and filamentous brown algae, and the copepod parasite Paradinium .Recently, another parasite was found to belong to Rhizaria, and in some ways its story represents the history of the group as a whole.
