抗菌肽及其在果蔬病害控制中的应用

Antimicrobial peptides and its application in the control of fruit and vegetable diseases

抗菌肽广泛存在于生物体内,是由基因编码、核糖体合成的具有抗细菌、真菌、病毒等多种生物学功能多肽,是生物体非特异性免疫功能的重要组成部分。随着人们对抗菌肽研究的深入,发现其有望成为抗生素、杀菌剂等的优良替代品。文章介绍了抗菌肽的来源分类、作用机制及其在果蔬病害控制中的应用,并展望了当前抗菌肽研究应用存在的问题。

Antimicrobial peptides are widely present in the organism,which are gene-encoded,ribosomal synthesized polypeptides.Antimicrobial peptides have anti bacteria,fungi,viruses and other biological functions.They are the important part of non-specific immune function of organism.With the development of the research on the antimicrobial peptides,they are expected to be excellent substitutes for antibiotics,fungicides.This review briefly introduces the classification,mechanism and application in the control of fruits and vegetables diseases of antimicrobial peptides,and prospects the problems existing in the research and widely application.
