Independent recruitment of a flavin-dependent monooxygenase for safe accumulation of sequestered pyrrolizidine alkaloids in grasshoppers and moths. [PDF]
PLoS ONE, 2012 Several insect lineages have developed diverse strategies to sequester toxic pyrrolizidine alkaloids from food-plants for their own defense. Here, we show that in two highly divergent insect taxa, the hemimetabolous grasshoppers and the holometabolous ...

Genotoxicity of pyrrolizidine alkaloids [PDF]
Journal of Applied Toxicology, 2010 AbstractPyrrolizidine alkaloids (PAs) are common constituents of many plant species around the world. PA‐containing plants are probably the most common poisonous plants affecting livestock and wildlife. They can inflict harm to humans through contaminated food sources, herbal medicines and dietary supplements.
