- Drought stress increases Fusarium crown rot (FCR) severity in wheat, and FCR worsens drought damage.
- The TaMPK3 gene shows opposite expression patterns under drought and FCR stress.
- TaMPK3 positively regulates FCR resistance but negatively affects drought tolerance.
- Knocking out TaMPK3 eliminates the synergistic damage between drought and FCR.
- TaMPK3 modulates TaWRKY26 to regulate sterol synthesis gene clusters, influencing FCR resistance.
- The key gene TaCYP51H37 within these clusters enhances FCR resistance.
- TaMPK3 reduces drought tolerance via the ABA signaling pathway.
- A molecular model is proposed where TaMPK3 mediates synergistic damage from drought and FCR.
