1. A plant comprising a nucleotide sequence encoding a Cry2Ab Bacillus thuringiensis δ

  • -endotoxin protein comprising a plant functional promoter sequence operably linked to a first polynucleotide sequence encoding a plastid transit peptide, which linked in-frame to a second polynucleotide sequence encoding said Cry2Ab Bacillus thuringiensis δ

    -endotoxin protein, said second polynucleotide sequence being operably linked to a plant functional 3′

    end transcription termination and polyadenylation sequence, wherein expression of said nucleotide sequence in said plant yields a fusion protein comprised of an amino-terminal plastid transit peptide covalently linked to said δ

    -endotoxin protein, and said plastid transit peptide functions to localize said δ

    -endotoxin protein to a plastid.
