| Outline of Final Research Achievements |
Various medicinal, tropical, and subtropical plant species were screened for phytotoxic volatile compounds in order to find novel candidate compounds for next-generation herbicides, and the characterization of several promising compounds including eucarvone, hinokitiol, cumin aldehyde, and octyl acetate was investigated to understand their modes of action. Eucarvone, hinokitiol, cumin aldehyde, and octyl acetate, which have carbonyl function, induced overproduction of reactive oxygen species (ROS) and oxidative damage in the susceptible plant species. However, it was proposed that the effects of these compounds were brought about by different mechanisms.
