Proteinaceous and Polyketide Compounds in Plant Protection 113(AMPM) have been classified into several groups of linear and cyclicpeptides (fungal defensins, bacteriocins, peptaibols, cyclopeptides andpseudopeptides) based on their most essential structural characteristics,and have been inventoried according to name, composition and producermicroorganisms (Montesinos, 2007).The efficacy of the natural antimicrobial peptides produced by biocontrolmicroorganisms towards various plant pathogenic bacteria, fungi andoomycetes in vitro and in vivo has been well documented (Table 5.1).Table 5.1.
