Gm crops in India: the science, controversy, and future of transgenesis

Transgenesis, the process of introducing a foreign gene (a transgene) into a living organism, stands at the forefront of modern biotechnology, promising revolutionary changes in agriculture and medicine. This technology allows scientists to confer specific, desirable traits—such as pest resistance, enhanced nutrition, or drought tolerance—to plants and animals far more directly than traditional breeding. While Bt Cotton remains India’s sole commercially cultivated transgenic crop, the landscape is undergoing a seismic shift, driven by recent policy developments and scientific breakthroughs in 2024-2025.

The core of transgenesis lies in Recombinant DNA (r-DNA) technology. Scientists identify and isolate a gene of interest (e.g., the Cry gene from the bacterium Bacillus thuringiensis which is toxic to bollworms) and insert it into the genome of a target organism. The resulting organism is known as a Genetically Modified Organism (GMO) or a transgenic organism.

The Shifting Regulatory Landscape in India (2024-2025 Focus)

The debate around GM crops in India has been reignited by significant recent events. While Dhara Mustard Hybrid-11 (DMH-11), a transgenic herbicide-tolerant mustard variety, received environmental clearance from the Genetic Engineering Appraisal Committee (GEAC), its commercial release has been stalled by legal challenges citing biosafety and environmental concerns. In response to ongoing litigation, the Supreme Court in 2024 directed the government to formulate a comprehensive national policy on GM crops, signaling a potential move towards a more structured and predictable regulatory environment.

Simultaneously, the Department of Biotechnology has recognized the distinction between traditional GMOs and organisms developed using newer gene-editing technologies like CRISPR-Cas9. These technologies allow for precise edits to an organism’s own DNA without necessarily introducing foreign genes, potentially offering a less controversial path forward. In 2025, this distinction became a focal point of debate with the release of gene-edited rice varieties, highlighting the tension between rapid innovation and the need for robust safety protocols.

Fun Fact: The first genetically modified animal, a mouse, was created in 1974, but the first GM food sold to consumers was the Flavr Savr tomato in 1994, which was engineered for a longer shelf life.

Applications and Mnemonic

Transgenic technology has vast applications, from creating pest-resistant crops to developing animals that can produce pharmaceuticals in their milk, a practice known as pharming.

To remember the key steps in creating a transgenic organism, use the mnemonic I-I-I-S-V:

• Isolate the gene of interest.
• Insert it into a vector (like a plasmid).
• Introduce the vector into the target cell.
• Select the successfully modified cells.
• Verify the trait in the whole organism.

Analogy: Think of an organism’s genome as a massive library of instruction books. Traditional breeding is like finding two similar books and hoping their combined pages create a better story. Transgenesis is like being a precise editor who lifts a specific, powerful paragraph from a book in a completely different library (e.g., a bacterium’s) and pastes it exactly where it’s needed in your target book (e.g., a plant’s).

Critical Policy Appraisal

The path to adopting GM technology is fraught with complex considerations, balancing immense potential with significant risks.

| Critical Policy Appraisal | | :--- | :--- | | Challenges / Criticisms | Opportunities / Successes / Way Forward | | Environmental Risks: Potential for gene flow to wild relatives, creating “superweeds”; harm to non-target organisms. | Food Security: Increased yields and resilience to climate change can combat hunger and malnutrition (e.g., Golden Rice for Vitamin A deficiency). | | Farmer Livelihoods: High cost of patented seeds and dependence on multinational corporations can trap farmers in debt. | Economic Growth: Reduced pesticide use, lower input costs, and higher productivity can boost farmer incomes and agricultural GDP. | | Regulatory Gaps: Lack of long-term biosafety data and public trust in regulatory bodies like the GEAC. | Sustainable Agriculture: Engineering crops for drought tolerance and nitrogen fixation can reduce water and fertilizer use. | | Ethical & Health Concerns: Public apprehension about consuming “unnatural” food and the unknown long-term health impacts. | Policy Clarity: The development of a national GM policy (as directed in 2024) and clear guidelines for gene-editing can create a stable, science-based framework. |

Statistic: Globally, GM crops were planted on over 190 million hectares in 2019, with the primary crops being soybean, maize, cotton, and canola. This demonstrates widespread international adoption despite regional controversies.

Analytical Lens: UPSC Focus (Mains & Prelims)

Conceptual Basis

The primary legal framework governing transgenesis and GMOs in India is the Environment (Protection) Act, 1986. Under this act, the “Rules for the Manufacture, Use, Import, Export and Storage of Hazardous Microorganisms/Genetically Engineered Organisms or Cells, 1989” were notified. The Genetic Engineering Appraisal Committee (GEAC), under the Ministry of Environment, Forest and Climate Change (MoEF&CC), is the apex body constituted under these rules to approve the large-scale use and commercial release of GMOs. Internationally, India is a signatory to the Cartagena Protocol on Biosafety, which aims to protect biological diversity from the potential risks posed by living modified organisms (LMOs).

UPSC Integration: Connecting the Dots

• Polity & Governance: The GM debate touches upon federalism (agriculture is a state subject, leading to conflicts between central approval and state-level bans), the functioning of regulatory bodies (transparency and independence of the GEAC), and judicial oversight.
• Economy: This topic is central to agricultural economics, including food security, doubling farmers’ income, intellectual property rights (seed patents by companies like Monsanto/Bayer), and international trade dynamics.
• Environment & Ecology: Key linkages include biodiversity, the risk of invasive species, the impact on non-target organisms, and the potential for sustainable agriculture versus the risks of monoculture.

Expert Analysis

The future of Indian agriculture is inextricably linked to its stance on biotechnology. While the caution is warranted, a blanket ban on all genetic technologies may be counterproductive in an era of climate change and increasing population pressure. The long-term policy direction appears to be moving towards a bifurcated approach: a highly stringent, evidence-based regulatory path for transgenic crops, and a potentially more permissive framework for gene-edited varieties that do not contain foreign DNA. The success of this approach will depend entirely on building public trust through transparent, independent, and scientifically robust regulatory processes. The challenge is not just scientific but deeply socio-political.

Prelims Practice Question (MCQ)

Which of the following statements regarding the regulation of Genetically Modified Organisms (GMOs) in India is correct?

a) The Food Safety and Standards Authority of India (FSSAI) is the final authority for the commercial release of GM crops. b) The Genetic Engineering Appraisal Committee (GEAC) is a statutory body established under the Biological Diversity Act, 2002. c) The GEAC is chaired by the Union Minister of Agriculture and Farmers’ Welfare. d) The GEAC functions under the Ministry of Environment, Forest and Climate Change (MoEF&CC) and is the apex body for approving the commercial release of GMOs.

Answer: (d) Explanation: The Genetic Engineering Appraisal Committee (GEAC) is the apex regulatory body in India for GMOs. It functions under the MoEF&CC as per the “Rules for the Manufacture, Use… of Genetically Engineered Organisms, 1989” notified under the Environment (Protection) Act, 1986. FSSAI regulates GM food products but does not approve crop cultivation. The GEAC is not established under the Biodiversity Act and is co-chaired by the Special Secretary/Additional Secretary of MoEF&CC and a representative from the Department of Biotechnology (DBT).
