Identification, Genome Characterization, and Growth Optimization of Paenibacillus peoriae MHJL1 for Biocontrol and Growth Promotion of Cotton Seedlings.

ABSTRACT: Fusarium and verticillium wilt are the primary diseases affecting cotton plants, significantly reducing both the yield and quality of cotton. Paenibacillus spp. are crucial biocontrol strains for controlling plant diseases. In this study, Paenibacillus peoriae MHJL1, which could prevent the pathogenic fungi of fusarium and verticillium wilt and promote cotton growth, was isolated from the rhizosphere soil of cotton plants. Whole-genome analysis of strain MHJL1 identified 16 gene clusters for secondary metabolite synthesis, including fusaricidins with potent antifungal properties. By optimizing the fermentation process, the cell and spore numbers of MHJL1 were increased to 2.14 × 10⁸ CFU/mL and 8.66 × 10⁸ CFU/mL, respectively. Moreover, the antifungal abi
