Other claims from this paper (6)
- Mechanism ZmECT23 directly recruits the ZmCCR4-NOT complex to facilitate viral RNA decay.
- Mechanism SCMV NIa-Pro hijacks maize ZmeIF4A3 into viral replication complexes.
- Mechanism ZmeIF4A3 sterically blocks ZmMTA-mediated m6A deposition, preventing viral RNA degradation.
- Observation Mechanistic conservation is observed in potato virus Y and turnip mosaic virus.
- Observation eIF4A3 is identified as a key m6A regulator in plants.
- Recommendation eIF4A3 is suggested as a potential target for engineering m6A-based antiviral crops.
