Figure 1From: Application of RNA silencing to plant disease resistanceApproaches of the application of RNA silencing to plant disease resistance. (A) Expression of viral small RNA in host plants triggers antiviral silencing. (B) Sprayed bacterium-processed siRNAs confers resistance against virus. (C) Feeding on transgenic plants that carry RNAi constructs confers resistance against insect. As,antisense; P, promoter; s, sense.Back to article page
