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.

The sequence AAUAAA is a signal for cleavage to generate a 3’ end of mRNA that is polyadenylated. Addition of poly(A) to nuclear RNA can be prevented by the analog 3’–deoxyadenosine known as cordycepin
