Massive prevalence of viral DNA in Ectocarpus (Phaeophyceae, Ectocarpales) from two habitats in the North Atlantic and South Pacific
Ectocarpus, a cosmopolitan genus of filamentous marine brown algae, contains two species, E. siliculosus and E. fasciculatus. Both species are subject to virus infections, which either destroy the host's sporangia or persist in a latent state without visible symptoms. We used PCR amplification...
