Research advances on microbial control of kiwifruit bacterial canker
摘要
Abstract
Kiwifruit bacterial canker(KBC),caused by P.seudomonas syringae pv.actinidiae,is a devastating disease.Compared with chemical control methods,microbial-based disease control offers significant advantages,including exceptional environmental compatibility,robust sustainability,and a reduced likelihood of developing pathogen resistance.Through literature review,this article systematically summarizes the disease characteristics,pathogenic bacterium,and transmission routes,as well as the main microorganism species used in biological control,core biocontrol mechanisms,and practical applications of microorganisms in the biocontrol of KBC.The aim of this study is to provide theoretical support and practical guidance for the sustainable biocontrol of KBC.The results are as follows:(1)Biocontrol microorganisms are highly diverse.The microorganisms with control effects on KBC mainly included four categories:bacteria,actinomycetes,fungi,and bacteriophages.Among these,Bacillus and Pseudomonas(bacteria)and Streptomyces(actinomycetes)are the most widely used and exhibit significant efficacy.(2)The biocontrol mechanisms involve both direct and indirect pathways.Direct mechanisms include the secretion of antimicrobial peptides,antibiotics and other antimicrobial substances to dissolve pathogenic bacterial cell walls,blocking infection sites through nutritional competition and spatial occupation,as well as direct disruption of pathogen structure via parasitism;indirect mechanisms primarily involve the induction of systemic resistance in host plants to enhance resistance to KBC.Most highly effective biocontrol strains employ both mechanisms,demonstrating superior efficacy compared with strains relying on a single mechanism.(3)In the same study,the control efficacy and stability of composite microbial agents are generally superior to those of single microorganisms.The synergistic effects among different strains not only broaden the antimicrobial spectrum but also enhance the colonization rate and stress tolerance of the strains on plant surfaces.In summary,this article clearly identifies the core issues in the current field of KBC biocontrol and puts forward targeted recommendations.关键词
