Transposable elements (TEs) are ubiquitous inhabitants of eukaryotic genomes and their proliferation and dispersal shape genome architectures and diversity. Nevertheless, TE dynamics are often explored for one species at a time and are rarely considered in ecological contexts. Recent work with plant pathogens suggests a link between symbiosis and TE abundance. The genomes of pathogenic fungi ap...

The representative toadstool Amanita muscaria plays an important role in maintaining forest ecosystems by forming mutualistic associations with a variety of trees. A is also known for the poisonous properties its hallucinogenic constituents, namely, ibotenic acid, muscimol, and muscarin. Serious cases poisoning humans may involve deliria, hallucinations, seizures, (rarely) death. typical sympto...

a-Amanitin, a toxic substance from the mushroom Amanita phalloides, is a potent inhibitor of DNA-dependent RNA polymerase II (the nucleoplasmic form) from sea urchin, rat liver, and calf thymus. This compound exerts no effect on the activity of polymerase I (nucleolar form) or polymerase III (also nucleoplasmic). The inhibition is due to a specific interaction with polymerase II or with a compl...
