Cysteine protease is one of the well-studied proteolytic enzymes in plants. This class of protease has been implicated invarious physiological aspects of developmental stages in plants including seed germination, senescence, and disease immunity. Ahandful of studies assign plants cysteine protease in different molecular battlefield under a few selected pathosystems, and initiallyextricate complex molecular mechanism of resistance. Interestingly, the same type of proteases released by pathogens have beendemonstrated to play a crucial role in establishing disease infection in plants. Most of which target resistance proteins resulting eitherin an access to the hosts biochemical loot or cascades of signals for defense. As means of enabling and disabling host immunity, thisclass of protease is subject to diversifying selection, which is an intriguing outcome under natural host pathosystem. This paper summarizes the key roles of cysteine proteases in a few selected plant pathosystems. KCI Citation Count: 2
