Bt Brinjal is a transgenic brinjal created out of inserting a gene [Cry 1Ac] from the soil bacterium Bacillus thuringiensis into Brinjal. The insertion of the gene into the Brinjal cell in young cotyledons has been done through an Agrobacterium-mediated vector, along with other genes like promoters, markers etc. This is said to give the Brinjal plant resistance against lepidopteran insects like the Brinjal Fruit and Shoot Borer (Leucinodes orbonalis) and Fruit Borer (Helicoverpa armigera). It is reported that upon ingestion of the Bt toxin by the insect, there would be disruption of digestive processes, ultimately resulting in the death of the insect.
Bt Brinjal is being developed in India by M/s Mahyco [Maharashtra Hybrid Seeds Company]. Now, the company wants to take up large scale field trials with the permission of the GEAC in 2006-07. The importance of this development can be understood from the fact that no GM Brinjal has been released for an advanced stage of field trials in op
