photosynthesis, cell cycle regulation, cell motility, and non-Mendelian (chloroplast) inheritance. Given the importance of eukaryotic algae, there is surprisingly little information about viruses or viruslike particles (VLP) in these organisms. It is difficult to credit the first person who described a virus or VLP in a eukaryotic alga. The problem is complicated because early reports consisted solely of microscopic observations and, in some cases, cultures were not axenic. A few papers in the Russian literature as long as 30 years ago described a lytic activity in cultures of the green alga Chlorella pyrenoidosa (174, 224-226). This lytic activity was given the name "chlorellophage." However, these investigators acknowledged that their cultures were contaminated with bacteria. Furthermore, the chlorellophage had typical bacteriophage morphology (174, 224). Therefore, despite the name chlorellophage, the host for these particles is unclear. Several investigators, almost simultaneously, reported the presence of VLPs in eukaryotic algae in the early 1970s. Lee (73) described 50to 60-nm polyhedral particles in vegetative cells of the red alga Sirodotia tenuissima, Pickett-Heaps 586

“…In one instance, some particles were stalked and surrounded by a membrane (Pienaar 1976), strated. For prokaryotic blue-green algae, however, the whereas in three others tail-like appendages were present (Swale & Belcher 1973, Dodds & Cole 1980, Gromov & Mamkaeva 1981. The reported diameters for the icosahedral particles range from 22 to 500 nm.…”

An ultrastructural investigation has shown the presence of icosahedral virus-like particles (VLPs) in three species of Paraphysomonas and one species of Chromophysomonas. The VLPs appear to be responsible for the sudden collapse of enrichment cultures of these species. The possible relationship with particles in other algae which are known to be true viruses is discussed. Endophytic bacteria were also observed in two species of Paraphysomonas, where they occurred within distensions of the nuclear envelope. This is the first report of endophytic bacteria in this location in the algae.
