MICROBIOLOGY. For the article “Kinetic analysis of a complete poxvirus transcriptome reveals an immediate-early class of genes,” by Erika Assarsson, Jason A. Greenbaum, Magnus Sundström, Lana Schaffer, Jennifer A. Hammond, Valerie Pasquetto, Carla Oseroff, R. Curtis Hendrickson, Elliot J. Lefkowitz, David C. Tscharke, John Sidney, Howard M. Grey, Steven R. Head, Bjoern Peters, and Alessandro Sette, which appeared in issue 6, February 12, 2008, of Proc Natl Acad Sci USA (105:2140–2145; first published February 1, 2008; 10.1073/pnas.0711573105), the authors note that in Fig. 2, the y axis appeared incorrectly. The scale on the y axis should be 0–200. The corrected figure and its legend appear below.
Fig. 2.
The vast majority of annotated ORFs for VACV are expressed during infection. Shown are the number of ORFs whose transcription is initiated (bars) in uninfected cells (U) and at 0.5–24 hpi and the cumulative number of genes whose expression was detected by each time point (line).
