Abstract
Vectors and procedures are provided that enable genetic manipulation of the filamentous ascomycetes such as Aspergillus nidulans and Aspergillus niger. The systems of the invention permit transformation of various Aspergillus strains as well as the production and secretion of desired foreign proteins. Also provided are cosmid vectors which enable the isolation, cloning, sequencing and modifications of genes from the filamentous ascomycetes.
