The Bt brinjal is a suite of transgenic brinjals (also known as an eggplant or aubergine) created by inserting a crystal protein gene (Cry1Ac) from the soil bacterium Bacillus thuringiensis into the genome of various brinjal cultivars. The insertion of the gene, along with other genetic elements such as promoters, terminators and an antibiotic resistance marker gene into the brinjal plant is accomplished using Agrobacterium-mediated genetic transformation. The Bt brinjal has been developed to give resistance against lepidopteron insects, in particular the Brinjal Fruit and Shoot Borer (Leucinodes orbonalis)(FSB). Mahyco, an Indian seed company based in Jalna, Maharashtra, has developed the Bt brinjal.The genetically modified brinjal event is termed Event EE 1, and Mahyco have also applied for approval of two brinjal hybrids. The Event EE 1 was introgressed by plant breeding into various local varieties by University of Agricultural Sciences, Dharwad and Tamil Nadu Agricultural University, Coimbatore. Some of the cultivars of brinjal include: Malpur local, Manjari gota, Kudachi local, Udupi local, 112 GO, and Pabkavi local.[1] It was approved for commercialization in India in 2009, but - after an apparent public outcry and rounds of debates in which representatives from Mahyco, the scientific community, and NGO's spoke on the topic - the then Indian Environment Minister, Jairam Ramesh, facilitated a moratorium on its release until further, unspecified, tests were conducted. Bt brinjal was approved for commercial release in Bangladesh in 2013.An expert committee (EC-I) was set up in 2006 to examine the biosafety data presented by Mahyco. They concluded that while the current data demonstrated that Bt brinjal was safe and equivalent to its non-Bt counterpart, more studies were required to re-affirm the findings and further trials were needed to ascertain the benefits from Bt brinjal with respect to existing methods for pest management and pesticide reduction. They recommended that large scale trials be allowed to go ahead. In 2009, a second expert committee (EC-II) examined the data from these trials. They concluded that adequate safety tests had been performed, stating that "the benefits of Bt brinjal event EE-I developed by M/s Mahyco far outweigh the perceived and projected risks", and advised the Genetic Engineering Appraisal Committee (GEAC) to recommend commercialization of the Bt brinjal.The GEAC cleared Bt brinjal for commercialization on 14 October 2009. Following concerns raised by some scientists, farmers and anti-GMO activists, the government of India officially announced on 9 February 2010 that it needed more time before releasing Bt brinjal, with Indian Environment Minister Jairam Ramesh saying that there is no overriding urgency to introduce Bt brinjal in India.[6][7] On 17 February 2010, Jairam Ramesh reiterated that the Centre had only imposed a moratorium on the release of transgenic brinjal hybrid, and not a permanent ban, saying that “until we arrive at a political, scientific and societal consensus, this moratorium will remain”. Companies with any seeds of Bt brinjal will have to register the details with the government, and the National Bureau of Plant Genetic Resources (NBPGR) was made responsible for storage of all the Bt brinjal seeds in India. Independent testing labs are currently being set up.
Many controversies surround the development and release of genetically modified foods, ranging from human safety and environmental impacts to ethical concerns such as corporate control of the food supply and intellectual property rights. The brinjal is an important food crop for India, and the potential commercialization of a genetically modified variety has drawn support and criticism. Although it is a major food crop in India, brinjal production is relatively low with fruit and shoot borer infestation a major constraint to yield.[15] Proponents of the technology believe the Bt brinjal will have positive effects for the Indian economy and the health of the farmers. Field trials conducted on research-managed farms carried out by Mayhco and the Indian Council of Agricultural Research suggested a 42% pesticide reduction and a doubling of the yield was possible.[16] The economic gain for consumers, developers and farmers was estimated to potentially be US$108 million per year with an additional $3–4 million saved due to health benefits associated with decreased pesticide use.
