INSECTICIDAL PEPTIDES

摘要

Insecticidal peptides comprising the amino acid sequence CX<1>X<2>X<3>RECGSCX<4>CNX<5>WKGKCEX<6> (SEQ ID NO 1), where X<1>, X<2>, X<3>, X<4>, X<5> and X<6> are any amino acid; or a fragment thereof, or a homologue or variant or derivative of any of these are described and claimed together with nucleotide sequences encoding these peptides. They may be applied as insecticidal compounds in the form of compositions, or expressed in host cells in particular plant cells. Transgenic plants which express peptides of the invention are described.
