چکیده انگلیسی
For optimal expression of δ-endotoxins from Bacillus thuringiensis in plants, preferential changes in the codon sequences, and reduction in overall AT content in the nucleotide sequence of the genes is important. Reports suggest that sequences with such modifications cannot be overexpressed in bacteria. We report here that the modified genes can be overexpressed in a strain of Escherichia coli carrying extra tRNA genes for some of the codons occurring at high frequency in plant genes and less preferred in E. coli. We also demonstrate that proteins when expressed as fusion products with NusA protein, are obtained as soluble fraction rather than in inclusion bodies. This allows easy and accurate LC50 analysis on insect pests.
