As a part of defense response, plants produce a high number of toxic molecules, including antimicrobial peptides (AMPs), that kill pathogens by interaction with phospholipids and membrane permeabilization. Most of the natural antimicrobial peptides are 10 to 50 amino acids (aa) in length, range in size from 2 to 9 kDa, are positively charged, contain a high position of hydrophobic amino acid, and often display a helical structure
