Pathogens attack plant cells to divert resources toward pathogen proliferation. To resist pathogens, plant cells rely on multilayered signaling pathways that hinge upon the secretory pathway for the synthesis and trafficking of pathogen sensors and defense molecules. In recent years, significant strides have been made in the understanding of the functional relationship between pathogen response and membrane traffic. Here we discuss how the plant cytoskeleton and endomembranes are targeted by pathogen effectors and highlight an emerging role of membrane contact sites in biotic stress responses.
病原体攻击植物细胞，将资源转移到病原体增殖上。为了抵抗病原体，植物细胞依赖于多层次的信号通路，这些通路依赖于分泌途径来合成和运输病原体传感器和防御分子。近年来，人们在理解病原体反应和膜运输之间的功能关系方面取得了重大进展。在这里，我们讨论了病原体效应子如何靶向植物细胞骨架和内膜系统，并强调了膜接触位点在生物胁迫反应中的新作用。
