• Ribozyme / RNase P $

ightarrow$ (IV) Cleavage of RNA genome: Catalytic RNA molecules that specifically bind target viral RNA through complementary base pairing and cleave phosphodiester bonds.

• Coat Protein $

ightarrow$ (III) Interferes with uncoating: Transgenic expression of viral coat protein (CP-mediated resistance) prevents the disassembly and uncoating of invading virions upon initial cell entry.

• cDNA of RNA satellite $

ightarrow$ (I) Interferes with replication: Satellite RNAs attenuate symptom severity by competing with helper virus genomic RNA for viral replicase machinery.

• Antisense RNA $

ightarrow$ (II) Binds to RNA preventing function: Hybridizes with complementary sense viral mRNA or genomic RNA, blocking translation and triggering enzymatic degradation.

• Tomato, Bt $\rightarrow$ (IV) Heliothis armigera: Transgenic tomato expressing cry1Ac confers resistance against tomato fruit borer (Helicoverpa armigera).
• Maize, Bt cryII $\rightarrow$ (I) European corn borer: Transgenic Bt maize controls European corn borer (Ostrinia nubilalis).
• Sugarcane, Bt cryI $\rightarrow$ (II) Diatraea saccharalis: Engineered sugarcane controls the devastating sugarcane stalk borer (Diatraea saccharalis).
• Rice, Bt cry1 gene $\rightarrow$ (III) Striped stem borer: Transgenic Bt rice expressing Cry1Ab or Cry1Ac protects against striped stem borer (Chilo suppressalis).
