Genetic engineering of the filamentous fungus Aspergillus oryzae still requires more suitable selection markers for fungal transformation. Our previous work has shown that Agrobacterium tumefaciens-mediated transformation (ATMT) based on the uridine/uracil auxotrophic mechanism with pyrG as the selection marker is very efficient for gene transfer in A. oryzae. In the present study, we delete the hisB gene, which is essential for histidine biosynthesis, in A. oryzae via homologous recombination and demonstrate that hisB is a reliable
