FIGURE 4.

Most significantly affected M. incognita females dissected from tomato roots seven weeks after inoculation with treated J2s. Morphology of females derived from J2s treated without dsRNA (A), with dsRNA of the gfp gene (B) and with dsRNAs of the nematode genes xpo-2 (C), pash-1 (D), vig-1 (E), smg-2 (F), rha-1 (G), ppw-2 (H), and 2242 (I). Comparisons were made with females isolated from roots treated with no dsRNA and dsRNA of the gfp gene. Arrows point to malformed or underdeveloped females in different treatments. Scale bar: 2 mm.
