Root-knot nematodes (Meloidogyne spp.) cause significant global crop losses, with M. enterolobii being particularly aggressive due to its broad host range and ability to overcome many resistance genes. Mungbean, an important crop for both nutrition and economy, is highly susceptible to these nematodes. However, research on mungbean resistance to M. enterolobii is limited, and the underlying defense mechanisms remain unclear. In this study, we screened mungbean accessions and identified CPI with strong resistance to M. enterolobii. Transcriptome analysis revealed 2730 differentially expressed genes (DEGs) in CPI, compared to 1777 DEGs in the susceptible accession (Cry) 7 days post-inoculation. Gene ontology (GO) enrichment in CPI showed upregulation of genes involved in plant–pathogen interactions, hormone signaling, oxidative stress, and immune responses. Plant defense-related genes (e.g., WRKY, PAL, MAPK, POD, and PR) were significantly induced. Metabolomic analysis identified four secondary metabolites related to phenylpropanoid metabolism and lignification that were enriched in CPI. These immune responses and metabolites likely contribute to the enhanced resistance in CPI. Our findings offer valuable insights into the molecular mechanisms of resistance to M. enterolobii and provide a foundation for breeding new mungbean varieties with intrinsic resistance.
