Popis: The wide diversity of secondary metabolites known to exist throughout the plant kingdom has been partially attributed to plant-pest coevolution,1,2 although aspects of the process remain controversial.3 It is also known that fungal infections can elicit the production and accumulation of toxic plant secondary metabolites.4 The elaborate design of chemical defences in plants can involve mixtures of related structures in one biosynthetic class or multiple lines of chemical defence in a single plant species.5 For example, Chrysanthemum spp. contain several phototoxic thiophenes and acetylenes, cytotoxic sesquiterpene lactones, and insecticidal Pyrethrins and isobutylamides.6
