Microbial elicitors and effectors, as well as plant receptors and defence compounds, traffic at the interface of plants and microbes in pathogenic or mutualistic interactions. Net exocytosis appears to be required for surface enlargement of plasma membrane during accommodation of microbes in intact plant cells. By contrast, ligand-induced endocytosis of surface receptors operates in basal defence. The first layer of plant defence appears to depend on polarized transport of small molecules and on local secretion of defence proteins. In return, pathogen effectors target plasma membrane bound and intracellular proteins to inhibit extracellular host defences.
微生物激发子和效应子，以及植物受体和防御化合物，在致病或共生相互作用中于植物与微生物的界面处移动。在完整植物细胞中容纳微生物期间，质膜表面扩大似乎需要净胞吐作用。相比之下，配体诱导的表面受体胞吞作用在基础防御中起作用。植物防御的第一层似乎依赖于小分子的极性运输和防御蛋白的局部分泌。作为回报，病原体效应子靶向质膜结合蛋白和细胞内蛋白以抑制细胞外宿主防御。
