Abstract

The invention relates to an insecticidal protein, its gene encoding and the uses thereof. The protein comprises: (a) a protein consisting of an amino acid sequence shown by SEQ ID NO:2 or a sequence of amino acid residuses at positions 1 to 640 thereof; or (b) a protein derived from (a) by substitution, deletion, or addition of one or more amino acid residuses of the amino acid sequences in (a), and having insecticidal activity; or (c) a protein generated by the expression of nucleic acid molecules containing a sequence of amino acid residuses at the positions 1 to 1920 of SEQ ID NO:1; or (d) a protein generated by the expression of nucleic acid molecules containing a complementary sequence that hybridized with the sequence of nucleotides at the positions 1 to 1920 of SEQ ID NO:1 under stringent conditions. The protein has high expression level and strong toxicity against pests.
