Antimicrobial peptides (AMPs) have been characterized in various organs and plant species. However, few studies have investigated AMPs in the genus Capsicum , especially their biological activities and mechanism of action. AMPs are small proteins isolated primarily from plants and animals. AMPs are of great interest to researchers because of their potent antimicrobial activity due to their ability to interact with cell membranes. While some AMPs participate in innate immune response by providing a rapid line of defense against infection, others may bolster plant defense against certain pests and pathogens. The genus Capsicum contains a myriad of AMPs involved in plant defense with the potential for new antimicrobial molecules. In recent years, our group and others have isolated and characterized AMPs from seeds, fruits, leaves and roots of Capsicum plants. Herein, we describe the diff erent AMP families, like defensins, lipid transfer proteins (LTPs), thionins, proteinase inhibitors, and others, present in the genus Capsicum . We also discuss the current knowledge of their antimicrobial activity, mechanism of action, and possible uses as antimicrobial molecules and in plant biotechnology.
