Detection of dsRNA by Northern blot in banana tissue samples. Samples were collected at 1, 12, 24 and 48 h post-application, h3 corresponds to leaf #3 of banana the plant. Ctrl, corresponds to the dsRNA control (500 mg/L) with 1% Triton + 1% DMSO. Samples from each time point evaluated were processed individually, except those corresponding to 24 and 48 h post-application (hpa), which were analyzed together in a single Northern blot experiment
