- Sugarcane streak mosaic virus (SCSMV) P1 protein (P1SCSMV) targets the BES1 transcription factor to disrupt plant immunity.
- P1SCSMV binds to NbBES1, suppressing NbXTH1 transcription, which is crucial for xyloglucan production and DAMP-triggered immunity.
- Overexpression of NbXTH1 enhances plant resistance to infections by increasing xyloglucan levels and thickening cell walls.
- Reduced xyloglucan due to NbXTH1 downregulation weakens DTI responses and results in thinner cell walls.
- The study suggests using xyloglucan or NbXTH1 to engineer broad-spectrum disease resistance in crops.
