ANTIBODIES FOR THE CONTROL OF CYST NEMATODES AND TRANSGENIC PLANTS EXPRESSING THEM

摘要

The invention concerns antibodies directed against an antigenic subventral salivary protein of a cyst nematode, e.g. of the genera Heterodera, Globodera and Punctodera, or at an immunogenic part or equivalent thereof, said antigenic protein having an amino acid of 30-50 kDa and having an isoelectric point (pI) of about 6.8 to 8.7. Furthermore provided are expression systems comprising at least a nucleotide sequence encoding an antibody or antibody fragment against a cyst nematode salivary protein, and a sequence regulating expression of said nucleotide sequence, for transforming plants so as to protect them against cyst nematodes.
