The characterization of AMEP412 for its HR activity. a The minimum concentration of AMEP412 for its HR activity. Serial dilutions of AMEP412 (2.4, 2.0, 1.6, 1.2, 0.8 and 0.4 mg mL−1) were infiltrated into tobacco leaves, and HR was observed after 24 h. b The thermal stability of AMEP412 for its HR activity. AMEP412 was treated at different temperatures (25, 40, 60, 80 and 100 °C) for 5 min, infiltrated into leaves and photographed at 24 h
