Abstract
A DNA fragment, encoding all or an insecticidally-effective part of a Bt crystal protein, is modified by changing A and T sequences to corresponding G and C sequences encoding the same amino acids.
Claims13
A modified DNA sequence encoding a Bacillus thuringiensis Bt2 insecticidal crystal protein (ICP) or an insecticidally effective fragment thereof, which comprises the DNA sequence of SEQ ID No. 23 from nucleotide position 705 to nucleotide position 1016.
A modified DNA sequence encoding a Bt2 protein or an insecticidally effective part thereof, wherein A and T nucleotides are changed to G and C nucleotides in about 63 codons of the DNA sequence corresponding to the DNA sequence from nucleotide 778 to nucleotide position 1089 of SEQ ID No. 22.
