Exploring Two Streptomyces Species to Control Rhizoctonia solani in Tomato

Streptomyces species are effective biocontrol agents toward many plant pathogens. These microorganisms well known for producing secondary metabolites, promoting growth and inducing defense mechanisms. In this study, the ability of tomato root-colonizing strains to trigger resistance against Rhizoctonia solani (J.G. Kühn) AG4 was investigated. For goal, we evaluated pattern LOXB PAL1 genes expression changes upon pathogen inoculation in primed plants. The results revealed that globisporous (Krasil’nikov) strain F8 S. praecox (Millard Burr) R7 were able enhance lipoxygenase phenylalanine ammonia lyase This finding suggests may jasmonic acid phenyl propanoid signaling pathways plants, therefore, resulting an induced status tomatoes R. solani. Biochemical characterization these showed they strong producers siderophores. produced siderophores hyderoxamate catechol types a phenolic siderophore. Moreover, also protease while only produce amylase. Taken together, indicate promote reduces disease hence suitable future depth field studies with aim attain appropriate protect
