Abstract

Mechanisms related to biotic interactions, such as pathogen attack, herbivory and symbiosis are important challenges to higher plants and have been widely studied especially for breeding purposes. The present review focuses on a special category of defense molecules, the plant antimicrobial peptides, providing an overview of their main molecular features and structures.
