Abstract: The present disclosure provides an antimicrobial peptide (AMP) for controlling Pseudomonas syringae pv. actinidiae (PSA) and a preparation method and use thereof, belonging to the technical field of biological control. In the present disclosure, the AMP has an amino acid sequence of Trp-Trp-Lys-Leu-Leu-Arg-Lys-Leu-NH2, and has a typical amphiphilic structure. The AMP can target a cell membrane of the PSA, increasing permeabilization and dissipating a membrane potential, which leads to calcium ion leakage. The AMP also acts on intracellular targets, affects DNA functions, reduces an activity of esterases, and induces the generation of reactive oxygen species (ROS). The AMP has a minimal inhibitory concentration (MIC) of 3.13 ?g/mL and a half maximal effective concentration (EC50) of 1.67 ?g/mL for the PSA, showing an activity significantly higher than that of agricultural streptomycin.
