Arginine- and lysine-rich peptides: synthesis, characterization and antimicrobial activity
In recent years, the multi-drug resistance of bacteria and fungi strains has become a worldwide problem. The incidence of fungal and bacterial infections is experiencing a serious growth and the microorganisms have developed several new mechanisms of antibiotic resistance. Antimicrobial peptides (AMPs) constitute one of the well-known barrier defense systems of plants. They have been isolated from roots, seeds, flowers, stems and leaves of a wide variety of species and have activities towards phytopathogens, as well as against human pathogens.
