Abstract

The invention opened an antiworm fusion gene which includes the nucleotides sequence with encoding the BT crystalline toxin and the Vip3 toxin from 5'-3'. The two sequences are in the same open reading frame. The BT crystalline toxin is the whole long or the active toxin without C end. The invention also opened the use of the fusion gene in the antiworm plants.

Description

technical field

[0001] The invention relates to an insect-resistant fusion gene, a fusion protein encoded by the insect-resistant fusion gene, and specific applications of the fusion protein. Background technique

[0002] Pests cost global agricultural production an estimated $8 billion per year. The control of pests currently mainly relies on the use of chemical pesticides, but pesticide residues will cause harm to human health. Therefore, people have successfully selected transgenic crops using insecticidal toxins for insect resistance. At present, transgenic insect-resistant corn and cotton have been planted in large quantities.

[0003] The key technology for transgenic crops to resist insects is to obtain insecticidal proteins with excellent performance, and there are many kinds of insecticidal proteins. More commonly used are Bt crystal proteins (Note 1), such as Cry1Ab, Cry1C, etc., which have been widely used in transgenic insect-resistant crops. However, it has b...
