摘　　要：1.Introduction As the central organelle in the eukaryotic secretory pathway,the endoplasmic reticulum(ER)mediates cellular processes that include calcium homeostasis and protein processing[1,2].The infection of plants by pathogens can induce ER stress and trigger the unfolded protein response(UPR).The UPR is a conserved protective signaling pathway that leads to programmed cell death(PCD)under extreme conditions[3–5],which can harm or benefit pathogens,depending on the timing and mode of cell death,and on whether the pathogen has physiologically adapted to benefit from the dying tissue[6].The biosynthesis and proper function of plant pattern recognition receptors(PRRs),which perceive pathogen-or microbe-associated molecular patterns(PAMPs or MAMPs)at the cell surface,also rely on N-glycosylation and the ER quality-control(ERQC)system[7–9].However,pathogens have evolved the capacity utilizing effectors to bind to the host ER stress pathway and manipulate it to their advantage during infection.
