Viruses infecting higher plants are among the smallest viruses known and typically have four to ten protein encoding genes. By contrast, many viruses that infect algae (classified in the virus family Phycodnaviridae) are among the largest viruses found to date and have up to 600 protein encoding genes. On pages 8–15 James L. Van Etten and David D. Dunigan review one group of large, icosahedral, plaque-forming phycodnaviruses that infect unicellular chlorella-like green algae. In many respects, chlorovirus infection resembles bacterial infection by tailed bacteriophages more than viruses that infect eukaryotes, i.e., they are not your everyday plant virus. The PBCV-1 virus reconstruction shown on the cover is by Xinzheng Zhang, Mickael Cherrier, Victor Kostyuochenko and Michael Rossmann, Purdue University. Cover design by Susanne C. Brink.
