According to the guard hypothesis, R gene products “guard” cellular proteins, which are called guardees or decoys

Guard hypothesis says that the Interaction between the guardees and the pathogen effectors is required for successful infection by the pathogen.

The NBS–LRR receptor remains inactive when bound to the guardee. However, when the effector interacts with the guardee, the NBS– LRR receptor becomes activated, triggering a signaling cascade that leads to the defense response.

R gene Mi-1 confers resistance to aphids and whiteflies

Rice R gene Bph14 confers resistance to the brown plant hopper

Melon R gene Vat confers resistance to the cotton aphid. 

All of these R genes encode NBS–LRR receptors.
