The Big Bang of picorna-like virus evolution antedates the radiation of eukaryotic supergroups
TLDR
The phylogenetic analyses of RNA polymerases and helicases presented in this Analysis article reveal close evolutionary relationships between RNA viruses infecting hosts from the Chromalveolate and Excavate supergroups and distinct families of picorna-like viruses of plants and animals. Expand
Isolation and Characterization of a Novel Single-Stranded RNA Virus Infecting the Bloom-Forming Diatom Rhizosolenia setigera
TLDR
Inter- and intraspecies host specificity tests revealed that RsRNAV is not only species specific but also strain specific and that its intraspecities host specificity is diverse among virus clones. Expand
Ma-LMM01 infecting toxic Microcystis aeruginosa illuminates diverse cyanophage genome strategies.
TLDR
The first sequenced freshwater cyanomyovirus genome of Ma-LMM01 is described, indicating that it is a member of a new lineage of the Myoviridae family and light is central in the phage-cyanobacterium relationships where the viruses use diverse genetic strategies to control their host's photosynthesis. Expand
Isolation and Characterization of a Cyanophage Infecting the Toxic Cyanobacterium Microcystis aeruginosa
TLDR
The host-phage system which the authors studied is expected to contribute to the understanding of the ecology of Microcystis blooms and the genetics of cyanophages, and the results suggest the phages could be used to control toxic cyanobacterial blooms. Expand
VIRUS PRODUCTION IN PHAEOCYSTIS POUCHETII AND ITS RELATION TO HOST CELL GROWTH AND NUTRITION
TLDR
Neither the infectivity of the progeny viruses produced nor the length of the lytic cycle appeared to be affected by the host cells' growth condltion, however, possible effects may have been obscured by low accuracy of infective virus counts or by low sampling frequency. Expand
Isolation of a virus infecting the novel shellfish- killing dinoflagellate Heterocapsa circularisquama
TLDR
The results demonstrate that viruses which infect and cause lysis of dinoflagellates are a component of natural marine viral com- munities. Expand
Effects of temperature and salinity on the growth of the red tide flagellates Heterocapsa circularisquama (Dinophyceae) and Chattonella verruculosa (Raphidophyceae)
TLDR
These novel flagellates have a potential for future outbreaks of red tides in pre- viously unaffected waters and a significant temperature-salinity inter- action on growth was found by factorial analysis. Expand
Algal Viruses with Distinct Intraspecies Host Specificities Include Identical Intein Elements
TLDR
Observations suggest the occurrence of horizontal transfers of inteins between viruses of different families and between archaea and viruses and reveal that viruses might be reservoirs and intermediates in horizontal transmissions ofinteins. Expand
Previously Unknown Virus Infects Marine Diatom
TLDR
It is shown that a viral infection can occur in the genus Chaetoceros and should therefore be considered as a potential mortality source, and supports the view that the ocean is a treasury of undiscovered viruses. Expand
Quantitative and qualitative impacts of viral infection on a Heterosigma akashiwo (Raphidophyceae) bloom in Hiroshima Bay, Japan
TLDR
It isuded that the viral infection was one of the most important factors determining quantity (biomass) and quality (clonal composition) of the H. akashiwo population. Expand
