摘要:
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 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:
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.
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.
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.
