Abstract : The marine cyanobacteria Prochiorococcus and Synechococcus are numerically dominant primary producers in the oceans. Each genera consists of multiple physiologically and genetically distinct groups (termed ecotypes in Prochiorococcus). Cyanobacterial viruses (cyanophages) that infect Synechococcus are abundant (to 104.106 phage ml.I) in the oceans and calculations suggest that they play a small but significant role in host mortality. Cyanophages are also thought to shape their host populations through regulation of sub-populations and through transfer of genes.
