Kind: research · Impact: low

## In brief

- A study in Nature Plants reports that viral infection in tomato increases transcription of the DCL2b gene.
- The same study reports that infection shifts the localisation of the DCL2b protein.
- The authors state that this relocalisation strengthens antiviral defence in tomato.

## Why it matters

It clarifies how a central Dicer-like protein in antiviral RNA silencing responds to infection in a major crop plant, which may inform future work on plant virus resistance.
