Filamentous fungi are widely used in biotechnology as cell factories for the production of chemicals, pharmaceuticals and enzymes. In order to improve their productivities, genetic engineering strategies can be powerful approaches. Different transformation techniques as well as DNA- and RNA-based methods to rationally design metabolic fluxes have been developed for industrially important filamentous fungi. However, the lack of efficient genetic engineering approaches still forms an obstacle for a multitude of fungi producing new and commercially interesting metabolites. This review summarises the variety of options that have recently become available to introduce and control gene expression in filamentous fungi and discusses their advantages and disadvantages. Furthermore, important considerations that have to be taken into account to design the best engineering strategy will be discussed.
