Patulin and citrinin quantification and gene expression using qPCR for WT and ΔkdmB strains in YES media. (A) Patulin and (B) Citrinin were extracted and quantified using an HPLC from YES media plates at 3 and 7 dpi. (C) Gene expression of the patulin backbone genes patL (transcription factor), patK (polyketide synthase, and patN (isoepoxydron dehydrogenase). (D) gene expression of the citrinin backbone genes ctnA (transcription factor), citS (polyketide synthase), citC (oxidoreductase). Error bars denote standard deviation of the mean.
