The miR863-3p diminishes the transcripts of atypical receptor-like pseudokinase1 (ARLPK1) and ARLPK2, the negative immune regulators during the early stages of infection, and silences SERRATE, a positive regulator of the plant immunity during the late stage of infection to promote immunity against P. syringe [42] through sequential silencing and feedback inhibition. The gene discussed is SRRT; the disease is infection.
