Other claims from this paper (8)
- Mechanism Compounds that combat pathogens, deter herbivores or act as allelochemicals provide selective advantage.
- Observation Compounds with little or no selective advantage are discarded.
- Observation Asteridae show reduction or elimination of alkaloids, flavonols and proanthocyanidins or tannins.
- Observation Asteridae show introduction and further methoxylation of 6-deoxy and 6-oxyflavones.
- Observation Asteridae show introduction of iridoids, especially aucubins.
- Observation Asteridae developed volatile oils rich in sesquiterpenes.
- Observation Asteridae increasingly rely on quinones as antimicrobials and allelochemicals.
- Observation Advanced Asteridae groups possess a specific assortment of antimicrobials, bitter substances and allelochemicals.
