clinker [34] comparison between definitively linked maleidride BGCs (through gene knockout or heterologous expression), as well as those identified from the genomes of confirmed maleidride producing strains. The T. stipitatus cluster 2 is included as it is likely to be responsible for rubratoxin biosynthesis (see Additional file 1: Fig. S35). Links between homologous genes are shown using their specific colour, except for the PKSs where the links are shown according to the percentage identity (see identity scale bar). Links between transport and regulatory genes have been removed for clarity. See Additional file 1: Table S1 for putative functions for uniquely encoded proteins and accession numbers for all proteins
