  • Patent number: 7387888
    Abstract: The present invention relates to isolated strains of a Streptomyces spp. which are endophytes of dicotyledonous plants and to methods for selecting such strains. The present invention also relates to a biologically active compound called coronamycin obtained from endophytic Streptomycetes isolated from higher plants. The present invention further relates to compositions of such compounds and to methods of protecting plants against attack by a plant pathogen and methods of inhibiting bacterial growth, fungal growth, viral infection, growth of parasitic organisms, and cancer cell growth with such compositions.

  • Patent number: 6942973
    Abstract: The present invention relates to methods for isolating a gene encoding an enzyme, comprising: (a) adding a mixture of labeled first nucleic acid probes from a microbial strain cultured on medium without the substrate, and labeled second nucleic acid probes from a microbial strain cultured on medium with the substrate, to an array of random nucleic acid fragments of the microbial strain where the labeled nucleic acids hybridize to complementary sequences of the genomic fragments in the array, wherein the first nucleic acid probes are labeled with a first reporter and the second nucleic acid probes are labeled with a second reporter; (b) examining the array under conditions wherein the relative expression of the genes of the microbial strain is determined by the observed hybridization reporter signal of each spot in the array; and (c) isolating a gene from the microbial strain that encodes an enzyme that degrades the substrate. The present invention also relates to isolated genes obtained by such methods.

  • Publication number: 20040197854
    Abstract: The present invention relates to methods for modifying the production of a polypeptide, comprising: (a) introducing a nucleic acid construct into a cell, wherein the cell comprises a DNA sequence encoding a polypeptide, under conditions in which the nucleic acid construct integrates into the genome of the cell at a locus not within the DNA sequence encoding the polypeptide to produce a mutant cell, wherein the integration of the nucleic acid construct modifies the production of the polypeptide by the mutant cell relative to the cell when the mutant cell and the cell are cultured under the same conditions; and (b) identifying the mutant cell with the modified production of the polypeptide.

  • Patent number: 6548274
    Abstract: The present invention relates to methods for producing a polypeptide, comprising: (a) cultivating a fungal host cell in a medium conducive for the production of the polypeptide; and (b) isolating the polypeptide from the cultivation medium; wherein the fungal host cell comprises a first nucleic acid sequence encoding the polypeptide in tandem with a second nucleic acid sequence comprising a crippled translational initiator sequence operably linked to a gene encoding a selectable marker, wherein the copy number of the first nucleic acid sequence has been increased by culturing the cell under conditions that select for multiple copies of the selectable marker. The present invention also relates to such fungal host cells and methods for obtaining such fungal host cells. The present invention further relates to nucleic acid constructs and vectors comprising a crippled translational initiator sequence operably linked to a gene encoding a selectable marker.
