Analysis of Bacterial Community Changes in Apple Trees Treated with Bacillus altitudinis KPB25, a Potential Biological Control Agent against Fire Blight.

ABSTRACT: The balance of microbial communities in an ecosystem is the most important factor representing its healthy state, even when immigrant microorganisms, such as biological control agent, are introduced into agricultural fields. Thus, this study aimed to investigate the potential of the antagonistic bacterium KPB25 (Bacillus altitudinis) as a biological control agent against fire blight by analyzing the changes in the epiphytic and endophytic bacterial communities of apple tree leaves following treatment. The KPB25 treatment resulted in increased community richness and diversity in endophytic bacteria. Conversely, in epiphytic bacteria, community diversity decreased after treatment. Beta-diversity analysis revealed that the endophytic community formed distinct clusters following KPB25 treatmen
