Implication

Randomized trial investigates biocontrol agent Pseudomonas fluorescens HT1 against Sclerotium rolfsii, suggesting effective management for southern blight.

Key Points

This study aims to evaluate the biocontrol potential of Pseudomonas fluorescens HT1 against the soilborne pathogen Sclerotium rolfsii.
VOCs produced by Pseudomonas fluorescens HT1 tested against Sclerotium rolfsii LC1.
Gas chromatography-mass spectrometry identified key VOC constituents.
RNA-seq analysis assessed the impact of VOCs on the transcriptome of S. rolfsii LC1.
VOCs inhibited mycelial growth of S. rolfsii by 88.31% and sclerotial germination by 79.17%.
Key VOCs included chloromethyl methyl sulfide and 2-methyl-5-(methylthio)-furan, exhibiting potent antifungal activity.
VOCs downregulated genes related to growth factors and transmembrane transport in S. rolfsii.
