Concept Note:

The development of new technologies has raised the potential of intervening in the genome to new heights. Theoretically, these technologies make it possible for genome editing to take place in all living organisms – be it a microorganism, a plant, animals, and even human beings. Unlike previous methods to change the gene, present technology makes genome editing more precise and can, in most cases, be inexpensive, effective, beneficial, and most importantly, accessible. It is these factors that raise important questions of how we wholly understand the concept of genome editing – its positives as well as associated risks, the ethical concerns inherent in undertaking such an endeavour, and its scope of application.

Genome editing applications promise significant benefits in agriculture – for consumers, this includes nutritional enhancement, improved food safety and reduced food waste; for farmers, this includes resistance to disease, weeds and pests, greater seed affordability due to cheaper seed production, and enhanced climate resilience including tolerance to drought; for society, this includes ecosystem services, such as increased biodiversity in cropping systems.

In understanding gene editing, also referred to as genome editing, we must clarify terminologies. While genetic modification and genome editing both alter the DNA of the subject, the methodologies and outcomes vary distinctly. Genetic modification involves the introduction of foreign material to modify the host genetic material, whereas genome editing involves minor deletions, insertions, and alterations in the same genetic material. Gene editing is a method to generate DNA modifications at precise genomic locations. These modifications can result in the knockout or knockdown of one or multiple genes without the permanent insertion of any foreign DNA. Transcription activator-like effector nucleases (TALENs), Zinc Finger Nucleases (ZFNs), and CRISPER/Cas systems have all been utilised to achieve precise gene edits.

Global warming-related climate change will have a significantly adverse impact on food production and biodiversity. One meta-review of more than 130 studies has estimated that one in six species may go extinct due to the changing climate. Genome editing provides options to address these problems by enabling greater survivability, resilience, disease resistance, better yield, and saving biodiversity. For example, engineering tomato architecture using CRISPR/Cas9 has enabled improvements such as drastically increased fruit size and altered plant morphology. By identifying and editing six genes associated with key domestication traits, researchers were able to domesticate a wild tomato relative, increasing fruit size 3–fold and fruit number 10–fold and yield while also improving nutrition, abiotic stress tolerance, and disease tolerance.

Nevertheless, GMO and Genome editing continue to raise many concerns in the context of ethics, preservation of nature and biodiversity, and issues of unintended consequences. The EU largely regards genome editing as a subset of genetic modification and is, as a result, circumspect with regulations. The European Court of Justice, in 2018, ruled that organisms obtained through mutagenesis (a newer method of genome editing) would not be excluded from the EU GMO Directive. The mandatory labelling of GMO ingredients in consumer products is another sticking point for European countries on GMOs. The US, on the other hand, takes a transnational approach to the debate. US companies like Monsanto, Dupont, Dow Chemical Company, Syngenta, and Pioneer enjoy an unrivalled monopoly over the GMO market and continue to push for greater adoption of GMOs in the European market.

India, on 30th March 2022, announced its decision to ease regulations governing genome-edited plants, excluding them from the laborious norms of genetically modified organisms. This move opens new vistas for using genome editing technologies to improve and increase crop production to meet the demands of overpopulation, food scarcity and depletion of soil fertility. India’s only tryst with GMOs has been the successful introduction of Bt Cotton into the market. Fear over the impact of the usage of GMOs could persist, in part, due to the long-term consequences India is experiencing because of the Green Revolution. While the immediate solution to the food security crisis India was facing at the time, over time, India’s usage of pesticides and inorganic fertilisers has risen. The soil, agricultural lands and crop production have been adversely impacted. India also lost nearly 1 lakh indigenous varieties of rice and saw a sharp decline in the cultivation of indigenous varieties of lentils and millets.

The debate in favour of genome editing – with its applications in disease prevention and treatments in humans, increasing yields and providing a solution to food security, building disease resistance, and improving product quality in both animals and plants – is met with questions on the risks of genome editing. The gene in any organism forms the core of a living being. Do humans have the right and authority to make changes to something as fundamental as an organism’s genome? Is genome editing technology the solution to the world’s current social problems and if yes, under what conditions would genome editing be safe for application? What impacts can we expect on biodiversity in undertaking the process of genome editing or genetic modification? And most importantly, given the experiences of the US and Europe union, where must India position itself in the debate? These will be some of the questions that this special lecture will seek to answer.

About the Distinguished Speaker:

Prof. S. Chandrasegaran PhD
Vice President – Science & Technology, TPF
Professor Emeritus, Bloomberg School of Public Health
Johns Hopkins University

Professor Srinivasan Chandrasegaran is a Managing Trustee and Vice President of Science & Technology at TPF. He is a Senior Scientist and Professor Emeritus of Genome Studies in the Department of Environmental Health and Engineering at Johns Hopkins Bloomberg School of Public Health in Baltimore, USA.

Dr. Chandrasegaran is an alumni of Presidency College, Chennai, and obtained his PhD in 1981 from Georgetown University. He is the inventor of the “Zinc Finger” methodology (ZFN) of synthetic genome editing. ZFNs offer a general way to deliver a targeted site-specific Double-Strand Break (DSB) to the genome. The ZFNs were originally developed in Johns Hopkins Laboratory under Dr S Chandrasegaran’s leadership. They have become powerful tools for enhancing gene-targeting in cells. He is leading teams that are working on the chemical synthesis of Chromosome IX.

He has published widely and innumerable research papers and is a frequent speaker on the subject across the world. His work has initiated a new era of “Biology by Synthesis”. This has huge potential for addressing India’s agriculture and public health requirements.
