Backgroud: Though it is toxic to humans, dichlorvos is a widely used chemical pesticide and plays an important role in the control of plant pests. The application of a combination of the biocontrol agent Trichoderma with dichlorvos may reduce the need for chemical pesticides. Therefore, revealing the specific molecular mechanism of Trichoderma tolerance to dichlorvos has become particularly important. Results: In this study, using transcriptome and metabolome analyses, changes in primary and secondary metabolisms in Trichoderma asperellum TJ01 were comprehensively studied in the presence of dichlorvos. A novel C2H2 zinc finger protein gene, zinc finger chimera 1 (zfcl), was discovered to be upregulated, along with a large number of oxidoreductase genes and ABC transporter genes under dichlorvos stress. In addition, gas chromatography-mass spectrometry (GC-TOF-MS), and liquid chromatography-mass spectrometry (LC-QQQ-MS) data revealed the global primary and secondary metabolic changes that occur in T. asperellum TJ01 under dichlorvos stress. Conclusions: The tolerance mechanism of T. asperellum TJ01 to dichlorvos was proposed. In addition, the absorption and residue of dichlorvos were analyzed, laying the foundation for elucidation of the mechanism by which T. asperellum TJ01 degrades pesticide residues.
