摘要:
The invention relates to a method of combating an animal parasite in a host which comprises delivering an anti-parasitic protein to the parasite or to a locus thereof by administering the protein to the host animal as a medicament or as a food. The anti-parasitic protein may be an inhibitor of an enzyme of the parasite, for example an inhibitor of a digestive enzyme such as a cysteine protease inhibitor. The parasite may be a helminth or a protozoan, for example, a nematode. According to one embodiment the anti-parasitic protein is expressed in a transgenic plant which may be a dietary crop for the host animal.

The invention relates to proteinase inhibitors and in particular cystatins which have been modified so as to enhance the effectiveness of synthetically manufactured counterparts. The modifications include either site-directed alterations in the structure of the protein and/or the production of hybrid molecules.
摘要:
This invention seeks to provide means by which transgenic plants harbour within their genome a chimaeric gene which when expressed produces a protein having a cytotoxic effect. Cytotoxicity is achieved by way of a protein or part thereof capable of blocking cellular protein synthesis, such as a maize ribosome inactivating protein or part thereof. The chimaeric gene may comprise a promoter operably linked to a sequence encoding a protein capable of blocking cellular protein synthesis such that the promoter is inducible at and/or adjacent to a target site.

A method of controlling nematodes, the method includes the steps of identification of a gene induced within a successfully infected plant by nematode infection of said plant and modifying the gene to confer nematode resistance to the plant.
摘要:
The invention is directed to a method for improving resistance or tolerance of a plant to a pathogen, wherein the method comprises integrating a DNA molecule encoding a fusion protein comprising at least two anti-pathogenic proteins or protein domains joined by at least one linker peptide, wherein the first anti-pathogenic protein or protein domain comprises Oc-I&Dgr;D86 or Oc-I and the second anti-pathogenic protein or protein domain comprises CpTI.
