Perception of MAMPs, phytocytokines, and pathogen-derived
phytocytokine-mimic peptides by PRRs induces the PTI signaling via acting on the
same infected cell, adjacent cells, or distal cells. Pathogen infections or MAMP
perceptions induce the production of DAMPs and phytocytokines, which further
modulate the PTI signaling. Phytocytokines (1) and pathogen mimicries (2)
mutually amplify MAMP-induced defense responses. Moreover, host-derived
phytocytokine (3) or pathogen-derived phytocytokine-mimic peptides (4) can
interfere with and attenuate the MAMP-or host phytocytokine-mediated immune
signaling. All figures were generated using BioRender (biorender.com).
