M. japonicus shows physical, chemical, and biotic resistance traits against herbivores. Trichomes, which are produced on leaf surfaces, serve as a physical resistance trait. Pellucid dots, which also are present on leaf surfaces, typically contain toxic metabolic substances or essential oils and function as a chemical resistance trait. Furthermore, the plant bears extrafloral nectaries (EFNs) on its leaf edges and food bodies (pearl bodies) on its leaf and stem surfaces as biotic resistance traits. EFNs contain primary sugars, and food bodies are known as lipid-rich particles. These biotic traits attract ants, which remove herbivores from the plant. The plant can change its combination of defence traits in response to leaf age and abiotic habitat conditions,.
