FIGURE 2

Heat map representing metabolite distribution in 55 A. flavus isolates. On the top of the figure, a dendogram is depicted, clustering A. flavus isolates as function of mating-type genes (MAT1-1 and MAT1-2) and metabolite occurrence. This figure was generated using the online metabolomics platform MetaboAnalyst 3.0 after the data were treated accordingly using sum normalization, log transformations and Pareto scaling. The data table was prepared using area under the curve (AUC) for each chromatographic peak of respective metabolites. Anq, anthraquinones; PKs, polyketides; NRPs, non-ribosomal peptides; IND-DITs, indole-diterpenoids; ST, sterigmatocystin; OMST, O-methylsterigmatocystin; DHST, dihydro-ST; DHOMST, dihydro-OMST; Asparas., asparasone A; Asper. OCH3, asperentin methyl-ether; 6,8-DMCIC, 6,8-dimethylcitreoisocoumarin; Asp. acid, aspergillic acid; Neoasp. acid, neoaspergillic acid; α-CPA, alfa-cyclopiazonic acid; Lep. B, leporin B.
