- Inactivating SnRK1β1A in rice promotes broad-spectrum disease resistance without affecting growth or yield.
- SnRK1β1A, a β subunit of SnRK1, increases susceptibility to multiple fungal diseases in rice.
- Fungal pathogens produce an effector-like protein, Gas2, which interacts with SnRK1β1A to prevent its degradation and promotes its nuclear translocation.
- SnRK1β1A inhibits SnRK1α1, a known positive regulator of broad-spectrum resistance in rice.
- Disrupting SnRK1β1A leads to resistance against several fungal diseases under normal farming conditions.
- The study suggests targeting inducible susceptibility genes as a strategy for durable disease resistance in crops.
