Protein Gene:- The gene of interest which codes for a particular protein in inserted in the genome of the corn. Bt genes produce Cry proteins in the corn. Promoter:- Along with the Bt gene, a promoter is also inserted into the corn.The function of the promoter is to control the Cry protein and it also sees that how much protein is produced by the plant.rticle Summary: Bt corn is a genetically modified crop. A protein is inserted into the plant's genome which is extracted from the bacterium Bacillus thuringiensis. This bacterium increases the soil fertility. When insects eat this plant, they get starved and die as a result....
Corn used for food has been genetically modified to tolerate various herbicides and to express a protein from Bacillus thuringiensis (Bt) that kills certain insects. About 90% of the corn grown in the U.S. was genetically modified in 2010.cientists discovered in 1946 that DNA can transfer between organisms. The first genetically modified plant was produced in 1983, using antibiotic-resistant tobacco. In 1994, the transgenic Flavr Savr tomato was approved by the FDA for marketing in the US.
