Is modulating virus virulence by induced systemic resistance realistic?

- Systemic acquired resistance against viruses: an uncertain fight with many targets.
- Induction of resistance to systemic viruses is a difficult task to be achieve.
- Alternative oxidase and salicylic acid orchestrate defense responses.
- Post-transcriptional gene silencing: complementary or alternative defense strategy?
- BTH, chitosan and rhizobacteria may be effective against systemic viruses.
