The biocontrol agent <i>Streptomyces rimosus</i> subsp. <i>rimosus</i> tempers shifts in the wheat spicosphere microbiome induced by Fusarium Head Blight.

ABSTRACT:

Introduction

Fusarium Head Blight (FHB) is a major fungal disease in wheat caused by Fusarium graminearum, inducing severe yield losses. Biological control agents (BCAs) can be an effective and sustainable approach to mitigate this phytopathogen. In this study, Streptomyces rimosus subsp. rimosus LMG19352 was used as a BCA to mitigate F. graminearum on wheat ears. Moreover, we aimed to assess the impact of BCA inoculation on non-target microorganisms present on the wheat spikes. Therefore, we evaluated shifts in the fungal and bacterial spicosphere microbiome (i) over time from flowering to mid-grain filling stage and (ii) across inoculations with F. graminearum and/or S. rimosus subsp. rimosus LMG19352.
