26-2 CAS Kunming Institute of Botany develops rapid detection method for poisonous mushrooms

While the toxic mechanisms of poisonous mushrooms vary, mushrooms containing cyclic peptide toxin dominate. They are encoded by the “MSDIN” gene family and ribosomally biosynthesized. A typical example are the cyclic peptide toxins of Amanita mushrooms, α-amanitin and phalloidin.

In China, among the cases of mushroom poisoning deaths, 80%-90% were caused by cyclopeptide toxins. Researchers at the CAS Kunming Institute of Botany have developed a rapid detection kit for these toxins based on a reaction, under acidic conditions, with lignin to produce a blue-green complex, which can be detected already after 3 min (patent application ZL201610991804.1).
