Fusarium graminearum is one of the most important pathogenic fungi with a wide range plant and animal hosts. This study investigated effects F. infection on rhizosphere microbiota growth two barley (Hordeum vulgare L.) cultivars, Baudin Kenpi 7, explored transplantation as strategy to enhance disease resistance. By exchanging surface microbiotas between varieties analyzing bacterial communities using 16S rRNA sequencing, researchers observed that increased diversity abundance, especially in barley. Growth indicators (root length, height, fresh/dry mass) also exhibited showed stronger Functional analysis underscored microbial community composition promoted metabolic pathways related resilience was associated improved seedling health. In contrast, 7 weaker resistance, emphasizing role seed-specific pathogen defense. An effective antagonistic strain, Bacillus amyloliquefaciens B1, isolated from barley, its inhibition rate against 80%. The results enhanced resistance low-diversity seeds, identified B. B1 promising biocontrol agent, providing potential application for sustainable agriculture reducing dependence chemical fungicides. highlights importance seed-associated plant–pathogen interactions provides basis development microbiota-based strategies mitigate crop diseases.
