Plant cystatins, also called phytocystatins, constitute a family of specific cysteine protease inhibitors
found in several monocots and dicots, where they can be involved in the regulation of several endogenous
processes and in defense against pests and pathogens, as well as in response to abiotic stress. In this mini-review we aimed
to present isolated and characterized phytocystatins with potential use in control of plant disease caused by fungi.
Keywords: Cysteine protease inhibitors, phytopathogenic fungi, plant cystatin, plant disease, plant-pathogen interaction.
