Proteases are an integral part of plant defence systems and their role in plant-pathogen interactions is unequivocal. Emerging evidences suggest that different protease families contribute to the establishment not only of hypersensitive response, priming, and signalling, but also of recognition events through complex proteolytic cascades. Moreover, they play a crucial role in PAMP/MAMP-triggered immunity as well as in effector-triggered immunity. However, despite important advances in our understanding of the role of proteases in plant defence, the contribution of proteases to pathogen defence in grapevine remains poorly understood. In this review we systematize the current knowledge of the main grapevine pathosystems and explore the role of serine, cysteine and aspartic proteases both from the host and pathogen point of views.
