Developing Aspergillus as a host for heterologous expression.
Filamentous fungi have long been used for production of a range of valuable products; with the advent of molecular biology, it became apparent that these fungi possess considerable potential as expression hosts for the production of heterologous proteins and small molecules. Aspergillus is an important genus, including well known species of economically significant molds, and widely used for basic genetic research. The development of a genetic engineering "toolkit" for Aspergillus, such as those existing for the simpler yeasts and bacteria, was delayed due to the added complexity of the filamentous fungi, and also to the lesser resources devoted to their study. History of the development of Aspergillus as an expression host, current state of the art and future directions are reviewed, touching on related research in other fungi when discussing the areas of greatest potential for future biotechnological applications, focusing on the large and diverse families of fungal secondary metabolites.
