This study introduces the immune response mechanism of cucumbers in response to biological stresses such as fungi, bacteria and viruses. Research has found that multiple transcription factors (such as WRKY, CRK), signaling pathways (such as jasmonic acid, ethylene, SA), antioxidant systems, and metabolites (such as glutathione, cucurbitacin) play key roles in the disease resistance process of cucumbers. Meanwhile, exogenous stimulants such as beneficial microorganisms and nano-selenium can enhance the resistance of cucumbers by activating defense genes and regulating reactive oxygen species metabolism. The application of molecular omics and transcriptomics has also promoted the discovery and functional research of disease-resistant genes. This study mainly sorts out the core mechanisms related to cucumber immunity, hoping to provide a theoretical basis for disease-resistant breeding and green prevention and control.
