Northern blot analyses of TMV RNA (A), CMV RNA (B), TMV siRNA (C), or CMV siRNA (D) of T4 transgenic plants before inoculation (-) or after inoculation with TMV or CMV. Wild type plant (wt) was used as a control. The size of the marker DNA oligomers (24nts) was presented on the left. The lower panel shows the loading level of each RNA sample by ethidium bromide staining.
