摘要:
There is provided a method for inhibiting growth and/or germination of a fungus, by contacting the fungus, or causing the fungus to be contacted with a composition including an effective amount of a pathogenesis-related protein occurring naturally in a plant. The protein has endochitinase activity, antifungal activity and a molecular weight of about 40 to 43 kDa as judged by Sodium Dodecyl Sulphate Polyacrylamide electrophoresis. There is also provided a composition for inhibiting growth and/or germination of a fungus. The composition includes a pathogenesis-related protein occurring naturally in a plant. The protein has endochitinase activity, antifungal activity and a molecular weight of about 40 to 43 kDa as judged by Sodium Dodecyl Sulphate Polyacrylamide electrophoresis. The composition also includes .beta.-1,3-glucanase in an amount sufficient to enhance the effectiveness of the composition in inhibiting the growth or germination of the fungus.
摘要:
Plants are provided with improved resistance against pathogenic fungi. They are genetically transformed with one or more polynucleotides which essentially comprise one or more genes encoding plant chitinases and .beta.-1,3-glucanases. Preferred are the intracellular forms of the said hydrolytic enzymes, especially preferred are those forms which are targeted to the apoplastic space of the plant by virtue of the modification of the genes encoding the said enzymes. Particularly preferred are plants exhibiting a relative overexpression of at least one gene encoding a chitinase and one gene encoding a .beta.-1,3-glucanase.
