Transport and secretion in plant-microbe interactions

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.
