From: Use of the kojA promoter, involved in kojic acid biosynthesis, for polyketide production in Aspergillus oryzae: implications for long-term production

Fig. 1

Maps of the kojic acid biosynthesis cluster and the polyketide synthase (PKS) gene with the surrounding genes associated with spore pigment biosynthesis in Aspergillus species. Each gene is shown by box arrow. The estimated function, systematic gene name, and gene ID are denoted above, in, and below the box arrow, respectively. (a) The kojic acid biosynthesis cluster composed of three genes. Each promoter is shown by arrow. (b) Four species that are A. fumigatus, A. oryzae, A. nidulans, and A. niger are used for the mapping. The PKS genes are conserved among all four species, whereas genes of the other orthologs composing the spore pigment biosynthesis cluster in A. fumigatus are not almost located around the PKS gene in the other species. Only the laccase gene in A. oryzae is exceptionally located adjacent to the PKS gene
