  • Patent number: 5585238
    Abstract: DNA sequences from the Internal Transcribed Spacer of the ribosomal RNA gene region are described for different species and strains of Septoria, Pseudocercosporella and Mycosphaerella. Specific primers from within these sequences are identified as being useful for the identification of the fungal isolates using PCR-based techniques.

  • Patent number: 5559034
    Abstract: Novel plant proteins (SAFPs) which synergize the activity of antifungal antibiotics are identified. SAFPs are demonstrated to synergize antifungal antibiotics, such as nikkomycins, polyoxins and amphotericins. SAFPs alone also display antifungal activity against several species of fungi, including strains of Candida, Trichoderma, Neurospora and strains of the plant pathogens Fusarium, Rhizoctonia and Chaetomium. Synergistic antifungal compositions containing SAFP and antifungal antibiotics are provided. In particular, synergistic compositions of corn-SAFP (zeamatin), sorghum-SAFP (sormatin) or oat-SAFP (avematin) and nikkomycin are found to be effective as antifungal compositions, especially against the opportunistic human pathogen Candida albicans. Method for employing SAFPs and synergistic compositions containing them for the inhibition of fungi are provided. In addition, a method for purifying SAFP from grain meal is provided.
