  • Vectors and conditions which allow genetic transformation of cephalosporium
    Patent number: 4762786
    Abstract: A method for transforming Cephalosporium and other lower eukaryotes is disclosed. The method involves inserting a recombinant DNA cloning vector comprising a Saccharomyces cerevisiae transcriptional and translational activating sequence positioned for expression of hygromycin phosphotransferase into a host cell and then growing the host cell under selective conditions. The vectors optionally further comprise Cephalosporium ribosomal DNA and also sequences that allow for replication and selection in E. coli and Streptomyces.
