Unveiling the Genomic Features and Biocontrol Potential of Against Root Rot Pathogens.

species are among the most significant pathogens causing root rot in . In this study, a strain of was isolated from the rhizosphere soil of and subjected to whole-genome sequencing. Plate confrontation experiments were conducted to investigate the antagonistic effects of against , , and , the primary species causing root rot. Whole-genome sequencing revealed 10,774 predicted genes in , of which 454 were associated with carbohydrate-active enzymes (CAZymes) involved in fungal cell wall degradation. Additionally, 11 biosynthetic gene clusters (BGCs) associated with antimicrobial production were identified, highlighting the biocontrol potential of . In plate confrontation experiments, showed substantial inhibition rates of 68.07%, 70.63%, and 66.12% against , , and , respectively. Scanning electron microscopy suggested the hyperparasitism of against , which was characterized by spore production that adhered to the pathogen, thereby inhibiting its growth. These findings provide a theoretical foundation to enhance understanding of the biological control mechanisms of , supporting its potential applications in sustainable agriculture.
