A Viral Movement Protein Prevents Spread of the Gene Silencing Signal in Nicotiana benthamiana

(Cell 103, 157–167; September 29, 2000) We, the editors of Cell, were contacted by the corresponding author, David Baulcombe, who informed us that this paper contains an unacknowledged image duplication. The mock control (Mock:M) lane shown in the northern blot experiment in Figure 3D is the same as the mock control lane in Figure 5D. Dr. Baulcombe informed us that these two experiments were carried out at the same time, run on a single gel, and exposed on the same autoradiograph and that they shared a negative (mock) control run in a single lane. Therefore, Figures 3D and 5D present the relevant lanes of each experiment plus the sharedmock control. Dr. Baulcombe provided us with a copy of the original autoradiograph for these experiments. We have evaluated the data and confirmed his explanation for this duplication.
