We anticipate SCN bioassays should result in the identification of specific lines with enhanced SCN resistances. Correlating bioassay results and the population of siRNA within individual transgenic plants will allow us to predict how much siRNA target sequences are required to be effective in the suppression of SCN. Using different HG types in bioassays and reapplying nematodes from a single population on a continuous basis should answer whether the transgenes can provide durable resistance to diverse populations and HG types.
