Here we identify induced PR-genes upon pathogen infection, physiological assessment of the plant’s primary and secondary metabolism such as phytohormonal regulation, peroxidase, phenylalanine-ammonia lyase (PAL) activity, H2O2 production, phenolic compounds, deposition of lignin, and histological observations to monitor fungal invasion in eggplant at a biotrophic phase of V. dahliae. The gene discussed is TMEM37; the disease is infection.
