List of 552 Mycotoxins and associated Smiles and JOELib descriptors
<p>Mycotoxin list containing 552 compounds was created from a literature search. From the compound names, simplified molecular-input line-entry system (Smiles) data were automatically retrieved using the Python module PubChemPy (https://pypi.org/project/PubChemPy/https://pubchempy.readthedocs.io/en/latest/).The Smiles list obtained was used to identify physicochemical indicators for each mycotoxin by the JOELib tools included in the ChemMine platform. These descriptors focus on molecule composition (number of : atoms, halogen atoms, B atoms, Br atoms, Cl atoms, I atoms, F atoms, N atoms, O atoms, P atoms, S atoms, acidic groups, aliphatic OH groups, basic groups, bonds, heavy bonds, heterocycles, hydrophobic groups, NO<sub>2</sub> groups, SO groups, OSO groups, SO<sub>2</sub> groups), molecular structure (molecular weight, geometrical diameter, geometrical radius, geometrical shape coefficient, the calculated Kier Shape for paths with length one, the calculated Kier Shape for paths with length two, the calculated Zagreb Group Index 1, the Zagreb Group Index 2, the fraction of rotatable bonds) and interaction properties (the calculate Polar Surface Area, Octanol/Water partition coefficient (logP), molar refractivity, the number of Hydrogen Bond Acceptors 1, Hydrogen Bond Acceptors 2 , Hydrogen Bond Donors 1 , Hydrogen Bond Donors 2 ).</p> <p>This research was supported by the European Union : Interreg Agritox project EAPA-998-2018.</p>
Raw data from: Inter- and intra-specific variation in mycotoxin tolerance: A study of four Drosophila species
<p>Many mycophagous Drosophila species have adapted to tolerate high concentrations of mycotoxins, an ability not reported in any other eukaryotes. Although an association between mycophagy and mycotoxin tolerance has been established in many Drosophila species, the genetic mechanisms of the tolerance are unknown. This study presents the inter- and intraspecific variation in the mycotoxin tolerance trait. We studied the mycotoxin tolerance in four Drosophila species from four separate clades within the immigrans-tripunctata radiation from two distinct locations. The effect of mycotoxin treatment on 20 isofemale lines per species was studied using seven gross phenotypes: survival to pupation, survival to eclosion, development time to pupation and eclosion, thorax length, fecundity, and longevity. We observed interspecific variation among four species, with D. falleni being the most tolerant, followed by D. recens, D. neotestacea, and D. tripunctata, in that order. The results also revealed geographical variation and intraspecific genetic variation in mycotoxin tolerance. This report provides the foundation for further delineating the genetic mechanisms of the mycotoxin tolerance trait.</p>

Metabotyping of Andean pseudocereals and characterization of emerging mycotoxins
<p>Pseudocereals are best known for three crops derived from the Andes: quinoa (<em>Chenopodium quinoa</em>, Chenopods I), canihua (<em>C. pallidicaule</em>, Chenopods I), and kiwicha (<em>Amaranthus caudatus</em>). Their grains are recognized for their nutritional benefits; however, there is a higher level of polyphenism and the chemical foundation that would rely with such polyphenism has not been thoroughly investigated. Meanwhile, the chemical food safety of pseudocereals remains poorly documented. Here we applied untargeted and targeted metabolomics approach by LC-MS to achieve both: <strong>i</strong>) a comprehensive chemical mapping of pseudocereal samples collected in the Andes to classify them according to their chemotype; <strong>ii</strong>) a quantification of their contents in emerging mycotoxins. An inventory of the fungal community was also realized with the aims to better know the filamentous fungi present in these grains and try to parallel this information with the presence of the molecules produced, especially mycotoxins. Metabotyping permitted to add new insights into the chemotaxonomy of pseudocereals, confirming the previously established phylotranscriptomic clades: Chenopods I (clusters quinoa and canihua), and Amaranthaceae s.s. (cluster kiwicha). Moreover, we report for the first time the presence of mycotoxins in pseudocereals. Sixteen samples of Peru (out of 27) and one sample from France (out of one) were contaminated with Beauvericin, an emerging mycotoxin. There were several mycotoxigenic fungi detected, including <em>Aspergillus sp.</em>, <em>Penicillium sp.</em>, and <em>Alternaria sp.</em>, but not <em>Fusaria</em>.</p>
