Effect of RNAi on the pathogenicity of Radopholus similis. Plant height (a), above-ground plant weight (b), fresh root weight (c), number of nematodes in the rhizosphere (d) and root infection symptoms (e) of tomato plants 2 months after inoculation with 1000 nematodes treated under different conditions. CK: uninoculated healthy tomato plants; R36: inoculated with nematodes treated with Rs-cps dsRNA for 36 h; G36: inoculated with nematodes treated with non-endogenous egfp dsRNA for 36 h; WT: inoculated with untreated nematodes. The bars indicate the standard errors of the mean (n = 5), and different letters indicate significant differences (p < 0.05) between treatments
