Viruses, belonging to three morphotypes, that infect the globally abundant marine cyanobacteria Prochlorococcus and Synechococcus. As reported in this issue of PLoS Biology, photosynthesis genes are common in the genomes of these viruses. Furthermore, significant genetic exchanges occur between the viruses and their hosts, influencing photosystem evolution (see Chisholm et al.).
