Virus titer in wild-type and FEC-derived TME 7 (Oko-iyawo) plants challenged with GFP-VIGS and MeSPY1-VIGS at 9 DPI. a Virus titer determination by Southern blot and b qPCR performed on total DNA extracted from leaves of wild-type (resistant to CMD) and FEC-derived (susceptible to CMD) plants. c RT-qPCR expression analysis of MeSPY. Higher virus titer is detected in both GFP-VIGS and MeSPY1-VIGS-challenged FEC-TME7 (susceptible plants) compared to the wild-type TME 7. Primers used for labelling probes for Southern blotting and for qPCR and RT-qPCR assays are shown in Table 1. Bars show SE (n = 4). P, positive control, N genomic DNA from unchallenged plants. Samples from three infected plants were pooled to make one sample, and a total of 4 samples (from 12 plants) were used per treatment combination
