Received 19 January 2005/ Accepted 7 March 2005

Light was found to strongly influence the infection of a freshwater cyanobacterium (Synechococcus elongatus PCC 7942) by a contractile DNA phage named AS-1. Phage progeny production was correlated with the amount of light in the laboratory and occurred in a diel pattern under natural light. At least one effect of light on AS-1 infection is at the level of adsorption.
