Advances in the synthesis mechanism of goose paste peptides.

Highly toxic mushrooms can kill people because they contain toxins.
reporter son of the 21st was informed that the Chinese Academy of Sciences Kunming Institute of Plant Research, a research resultfound that belongs to different sections of highly toxic mushrooms, can synthesize the same, creepy "goose paste peptide", from the early stage of the gene level transfer event.
According to Luo Hong, associate researcher of the Key Laboratory of East Asian Plant Diversity and Biogeography of the Chinese Academy of Sciences, toxins are produced by mushrooms due to the need for self-survival, and they can drive away insects or other animals that are harmful to them, giving offspring spores the opportunity to mature and spread and reproduce. as a result of
, some mushrooms have evolved efficient "toxin production lines" that enhance their ability to survive and adapt.
as early as more than 100 years ago, people have found that the world's most toxic goose paste genus, helmet spore umbrella genus and ring-spore mushroom genus relatives are far away, respectively, under the taxonomics of three different sections, but can synthesize the same kind of toxin - goose paste peptide.
however, the three categories of highly toxic mushrooms, "goose paste peptide production line" how to evolve, but there is a lot of debate.
recently, a team of researchers at the Kunming Institute of Plant Research of the Chinese Academy of Sciences found that the mechanism of synthesis of goose paste peptides is much more than people think.
the ancestors of these poisonous mushrooms, who had experienced living in the same habitat in the early years, used the gene-level transfer method to "shanzhai" the genes of the highly toxic mushroom scorpion mushrooms or the highly toxic mushrooms close to the ring mushrooms to be added to their own genes, a mechanism that is so complex that it may take tens of thousands of years for other organisms to evolve.
study also found that the "shanzhai" came over the gene, from the ring mushroom to helmet spore umbrella to the goose paste step-by-step realization, goose paste finally obtained this toxin synthesis "secret recipe", but evolved the ability to synthesize new toxins, so its toxicity exceeds the helmet spore umbrella and ring-handled mushrooms, become "poison king", become the culprit of 90% of the mushroom poisoning deaths.
this study provides a basic scientific basis for the analysis of the toxic mechanism of highly toxic mushrooms, as well as the accurate mining and utilization of toxin resources based on genome and genetic engineering, and for the scientific detection and prevention of such mushroom poisoning.
research has been published online in the Journal of the International Society of Bacteria.
