Received 19 May 2005/ Accepted 14 July 2005

Four putative type IV pilus genes from the toxic, naturally transformable Microcystis aeruginosa PCC7806 were identified. Three of these genes were clustered in an arrangement which is identical to that from other cyanobacterial genomes. Type IV pilus-like appendages were also observed by electron microscopy.
