摘　　要：芽孢杆菌分泌的抗真菌肽(Antifungal peptide, AFP)对病原真菌有抑制作用,且具高效、安全特性。综述了AFP的主要种类、抑菌机制、分离纯化和鉴定技术及应用研究进展,并从AFP胞内响应机制、协同抑菌机制、生物合成途径、田间应用效果、提升AFP产量等方面提出了今后的研究方向,为生防芽孢杆菌菌剂及其AFP制剂在精准农业中的应用提供理论支持。Antifungal peptides(AFPs)secreted by Bacillus have inhibitory effects on pathogenic fungi and are highly effective and environmentally friendly.In this paper,the main types of Bacillus AFPs and the research progress on the antifungal mechanisms,isolation,purification and identification technology,and application were reviewed.The future research directions were proposed from the aspects of intracellular response mechanism,synergistic bacteriostatic mechanism,biosynthetic pathway,field application effect,and improvement of AFPs yield,to provide theoretical support for the application of biocontrol Bacillus agents and their AFPs preparations in precision agriculture.
