PLANT BIOLOGY Retraction for “RNA silencing of host transcripts by cauliflower mosaic virus requires coordinated action of the four Arabidopsis Dicer-like proteins,” by Guillaume Moissiard and Olivier Voinnet, which appeared in issue 51, December 19, 2006, of Proc Natl Acad Sci USA (103:19593–19598; first published December 12, 2006; 10.1073/pnas.0604627103).

The authors wish to note, “Recently, potential errors affecting some of our figures were brought to our attention. Through the inspection of the corresponding original raw data, we have confirmed there were errors in Figs. 1C and 2 B, Left, E, Top Left and Bottom, and F, Right. While we have also confirmed that Fig. 2 E, Top Right, and F, Left, are not erroneous, our own inspection of all the remaining figures revealed additional mounting mistakes.

“Although these errors could have been corrected with the original raw data and were recognized as inadvertent we, the authors, consider them too numerous and have thus decided to retract the study on this basis. We will seek to submit the corrected version of this article for peer review elsewhere.

“Olivier Voinnet, the corresponding author, takes full responsibility for the errors contained in the original publication. We deeply apologize for the inconvenience caused.”
