摘要： This study reports a strain of CCTCC-SBW0162 with potential to enhance biocontrol activity against gray mold pathogen, , and with a pivotal role in tomato ( ) plant growth enhancement. A total of 254 isolates were screened by antagonistic assay. Of these, 10 were selected for greenhouse experiments based on their greater inhibition of . The antagonistic assay and greenhouse experiments indicated that CCTCC-SBW0162 gave the highest inhibition rate (90.6%) and disease reduction (80.7%). Also, to study the possible mechanism associated with antifungal activity of CCTCC-SBW0162 against , molecular docking was used to assess the interactions between CCTCC-SBW0162-derived metabolites, and pathogencity and virulence related proteins of . The molecular docking results indicated that the combination of harzianopyridone, harzianolide and anthraquinone C derived from CCTCC-SBW0162 could synergistically improve antifungal activity against through the inhibition/modification of pathogenicity and virulence related proteins. However, this computerized modeling work emphasized the need for further study in the laboratory to confirm the effect derived metabolites against the proteins of and their interactions.
