East Lake,located in the middle and lower reaches of the Yangtze River,is a major source of drinking water for local residents. However,the large increase of population density and the rapid development of industry has resulted in heavy eutrophication of East Lake over the past few decades. Microcystis aeruginosa is a well-known toxic algae-blooming cyanobacterial species (Carmichael W W,et al.,2001) and a major player in the cyanobacterial water blooming in East Lake. Cyanophages are considered to be a significant factor in preventing algal blooming by causing the death and regulating the abundance,clonal diversity,and composition of their cyanobacterial host populations (Suttle C A,et al.,1992; Tucker S,et al.,2005).
