Wild boars have been reported as bioindicators for per- and polyfluoroalkyl substances (PFAS) in a variety of studies. However, data about PFAS levels wild from sites with limited industrial general human activity is scarce. In this study, boar (Sus scrofa) organs the Bohemian Forest National Park (Czech Republic) were used pollution. work, 29 livers 24 kidneys 30 (0.5–5 years) investigated using fluorine mass balance approach. For this, samples measured high performance liquid...
Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify diversity) with nomenclature name diversity). Two proposals amend International Code Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region extent) serve as taxon names voucherless fungi (mainly putative taxa from...
Psilocybin, psilocin, baeocystin, norbaeocystin, and aeruginascin are tryptamines structurally similar to the neurotransmitter serotonin. Psilocybin its pharmacologically active metabolite psilocin in particular known for their psychoactive effects. These substances typically occur most species of genus Psilocybe (Fungi, Strophariaceae). Even sclerotia some these fungi as "magic truffles" growing interest microdosing due them improving cognitive function studies. In addition studies,...
Since not only psilocybin (PSB) but also PSB-containing mushrooms are used for psychedelic therapy and microdosing, it is necessary to know their concentration variability in wild-grown mushrooms. This article aimed determine the PSB, psilocin (PS), baeocystin (BA), norbaeocystin (NB), aeruginascin (AE) concentrations a large sample set of belonging genera previously reported contain psychotropic tryptamines. Ultra-high performance liquid chromatography coupled with tandem mass spectrometry...
Metallothioneins (MTs) are cysteine-rich peptides involved in heavy metal tolerance of many eukaryotes. Here, we examined their involvement intracellular binding silver (Ag) the ectomycorrhizal fungus Amanita strobiliformis. The Ag complexes and peptide ligands were characterized using chromatography mass spectrometry. full-length coding sequences obtained from a cDNA library used for complementation assays yeast mutant strains. Abundance respective transcripts A. strobiliformis was measured...
Tuber aestivum is the most common European truffle with significant commercial exploitation. Its production originates from natural habitats and artificially inoculated host tree plantations. Formation of ectomycorrhizae in seedling roots often inefficient. One possible reason lack indigenous associative microbes. Here we aimed at metagenetic characterization cultivation prokaryotes associated T. a field transect cutting through fungus colony margin. Several operational taxonomic units...
Abstract Synthetic psilocybin (PSB), but also the PSB-containing mushrooms are used for psychedelic therapy and microdosing. It is necessary to know alkaloids variability stability in wild-grown mushrooms. Concentrations of other psychotropic (or potentially psychotropic) tryptamines such as psilocin (PS), baeocystin (BA), norbaeocystin (NB), aeruginascin (AE) relevant. This study aims determine concentrations PSB, PS, BA, NB AE a large sample set mushroom genera previously reported contain...
Tuber aestivum is becoming an important commodity of great economical value in some European countries. At the same time, it a highly protected organism other countries, where needs careful treatment. A reliable method detection roots and soil thus needed for assessment geographic distribution, ecological studies inoculation efficiency testing man-made experiments. PCR-based T. using specific primers was therefore developed. pair PCR Tu1sekvF/Tu2sekvR selective genotypes mesentericum...
Abstract This work describes the development of a novel method for quantitative mapping Hg and Se in mushroom fruit body tissues with laser ablation coupled to inductively plasma-mass spectrometry (LA-ICP-MS). Different parameters protocol preparation standards used quantification via external calibration were assessed, e.g., dissolution temperature gelatin addition chitosan l -cysteine as additives gelatin-based droplets better match sample matrix. While was not suited this purpose,...
Abstract The total arsenic mass fraction as well the speciation were studied in four different mushroom species with inductively coupled plasma spectrometry and high-performance liquid chromatography to spectrometry, respectively. Arsenic fractions detected mushrooms covering a range from 0.3 22 mg As kg −1 dry mass. For speciation, like arsenobetaine, inorganic arsenic, or dimethylarsinic acid found, which are commonly mushrooms, but it was also proven that recently discovered novel...
