Multi-omics analyses reveal the biocontrol potential of endophytic <i>Paenibacillus peoriae</i> 3-B4 against maize seedling blight.

ABSTRACT:

Introduction

Maize seedling blight, caused by the phytopathogenic fungus Fusarium verticillioides, is a common and rapidly spreading disease that reduces grain quality and yield. Control of this pathogen is challenging due to its complex infection process and the development of resistance to chemical pesticides. Biological control agents are therefore recognized as a sustainable and environmentally friendly strategy for the maize seedling blight.

Results

In this study, we isolated and identified Paenibacillus peoriae 3-B4 from maize leaves, which exhibited a 59.92% inhibitory rate against F. verticillioides in greenhouse co-inoculation conditions. Genome sequencing revealed a 5.91 Mb chromosome containing biosynthetic gene clusters involved in antifungal
