Schematic representation of the putative OTA biosynthetic gene cluster 38, located on scaffold 12 (931076-971429 nt). Arrows represent genes and point in the direction of transcription. The role of the polyketide synthase gene (AcOTApks), the non-ribosomal peptide synthetase gene (AcOTAnrps) and the halogenase gene (AcOTAhal) in the biosynthetic pathway of OTA has been determined by gene inactivation10,12,20. The cytochrome P450 monooxygenase gene (AcOTAp450) and the bzip transcription factor gene (AcOTAbZip) are putatively involved in OTA biosynthesis20,21.
