The study emphasizes the importance of genotype-specific responses to PGPB treatment and the mechanisms of drought tolerance in peppers. Pseudomonas putida A32 effectively mitigated drought stress in both genotypes, with differential responses influenced by plant genotype. Our study confirmed our initial hypothesis that Amfora 19, as a genotype tolerant to biotic stress, is also more tolerant to abiotic stress. Understanding these interactions is crucial for the development of customized strategies to improve plant productivity and tolerance to drought.
