To study the effect of antibiotic exometabolites of Bacillus amyloliquefaciens subsp. plantarum IMV B-7524 strain on the induction of defense responses in young plants of winter wheat. Methods. Microbiological, biochemical, phytopathological, statistical. Results. It was found that, when pre-watering winter wheat plants with salicylic acid, the cell-free culture supernatant and lipopeptide fraction of IMV B-7524 strain exometabolites during the further infection with phytopathogen Bipolaris sorokiniana, the damaged surface area of leaves decreased more than 10 times compared to the control. It was shown that in the roots and shoots of winter wheat plants L-phenylalanine ammonia-lyase (PAL) activity increased about 3 times in 2 hours after treatment. Conclusion. Reduction of the damaged surface area of leaves by the action of fungal phytopathogen and change of PAL activity in plants indicate the induction of defense responses under the influence of antibiotic exometabolites of B. amyloliquefaciens subsp. plantarum IMV B-7524 strain.
