Antibacterial and antifungal. May also create scent eg. menthol by mint plants
1 of 5
Phenols
Antibacterial and antifungal. Tannis in bark inhibit insect attack by binding to salivary proteins and deactivating enzymes. Insects ingest and lot and die, preventing transmission
2 of 5
Alkaloids
Nitrogen- containing compounds eg. caffine, nicotine. Bitter taste to inhibit herbivore feeding and inhibit enzyme action of metabolic activites. some inhibit protein synthesis, reducing grazing by larger animals
3 of 5
Defensive proteins(defensins)
Small cysteine-rich proteins, anti-microbial activity. Act on molecules in the plasma membrane of pathogens, inhibiting ion transport channels
4 of 5
Hydrolytic enzymes
Found in spaces between cells. eg. chitinases that break down chitin in fungal cell walls, gluconases that break glycosidic bonds and lysosomes that degrade bacterial cell walls
