The five-day International Symposium on “Harnessing Genome Editing for Resilient Agriculture” recently concluded at the Gurdev Singh Khush Institute of Genetics, Plant Breeding, and Biotechnology (GSKI-GPBB) at Punjab Agricultural University (PAU), Ludhiana. The event, held from March 3 to 7, saw participation from top scientists and experts from India, Canada, and Spain. The symposium aimed to explore and discuss the potential of genome editing in creating sustainable and resilient agricultural practices.
The event was organized under the Genome Editing for Food Security and Environmental Sustainability (GEFSES) training programme, a part of the Collaborative Research and Teaching Experience (CREATE) initiative. Funded by the Natural Sciences and Engineering Research Council of Canada (NSERC), the initiative brought together international researchers and academicians to collaborate on the latest advancements in genome editing technology.
Bringing Together Experts from Around the World
The symposium was a result of collaborative efforts between Punjab Agricultural University (PAU), Guru Angad Dev Veterinary and Animal Sciences University (GADVASU), Ludhiana, and McGill University, Canada.
Notable experts in plant and animal sciences shared their knowledge and findings. Among them was Dr. Kanwarpal S Dhugga, a former principal scientist at the International Maize and Wheat Improvement Center or CIMMYT, and Dr. Baljit Singh from the University of Saskatoon, Canada. Dr. Ian Affleck, Vice President of Plant Biotechnology at Crop Life, Canada, also provided insights on the regulatory and commercial aspects of gene editing in agriculture.
McGill University’s contributions included presentations from Dr. Jaswinder Singh, Dr. Raj Duggavathi, Dr. Jean-Benoit Charron, and Dr. Saji George. Additionally, Dr. Sharon Regan from Queen’s University, Canada, spoke on gene editing’s role in improving fruit trees, while Dr. Sergio Navarro Serna from Spain’s Centro de Biología Molecular Severo Ochoa, CSIC, Madrid, contributed valuable research on the subject.
Indian scientists also played a crucial role, with significant contributions from Dr. K.C. Bansal, former Director of the National Bureau of Plant Genetic Resources (NBPGR), and Dr. Wricha Tyagi from the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Hyderabad. Dr. Naveen Chandra Bisht from the National Institute of Plant Genome Research (NIPGR), New Delhi, also shared key insights on genome editing’s application in Indian agriculture.

The Role of Genome Editing in Modern Agriculture
Gene editing has emerged as a pioneering tool in agriculture, helping to develop crops that are more resilient to climate change, pests, and diseases. With the growing concerns over food security and environmental sustainability, gene editing allows scientists to modify plant and animal genomes precisely and efficiently. This technology is seen as an alternative to traditional genetic modification techniques, offering more targeted improvements with fewer regulatory concerns.
One of the biggest advantages of genome editing is its ability to enhance crop resilience. By precisely modifying genetic sequences, scientists can develop drought-resistant crops, reducing the dependency on excessive irrigation. Additionally, crops can be engineered to resist specific pests and diseases, decreasing the need for chemical pesticides and lowering environmental pollution.
Gene editing also improves crop yield and nutritional value. Scientists can alter plant genetics to increase essential nutrients, helping to combat malnutrition. For example, genome-edited rice can be enriched with higher levels of vitamin A, addressing deficiencies in many developing regions. Furthermore, genome editing accelerates breeding programs. Traditional breeding methods take years to develop improved plant varieties, whereas genome editing allows for rapid enhancements without the need for crossbreeding.
Challenges and Ethical Considerations
Despite its many benefits, genome editing also raises several concerns. One of the main issues is regulatory approval. Many countries still lack clear policies on gene-edited crops, leading to delays in their adoption. While some nations have embraced the technology, others remain skeptical due to public concerns over genetic modifications in food.
Another challenge is accessibility. Advanced gene editing technologies require skilled researchers and expensive laboratory setups, which may not be readily available in developing countries. This creates a risk of technological disparity, where only a few nations benefit from genome-edited crops.
Ethical concerns also play a role in the debate. Critics argue that genome editing could lead to unintended consequences, such as genetic mutations with unknown long-term effects. There are also concerns about large corporations controlling gene-editing patents, potentially limiting access to small-scale farmers.
A Platform for Knowledge and Innovation
Beyond scientific discussions, the symposium at PAU also provided a platform for students to engage and participate. MSc and PhD students showcased their artistic talents through music and dance performances during a cultural program. These activities highlighted the importance of integrating science with culture, fostering a holistic approach to education and research.
The symposium successfully brought together experts to exchange ideas and insights, strengthening global collaboration in genome editing research. As the world faces growing agricultural challenges, such platforms play a crucial role in shaping the future of sustainable farming.
The conclusions drawn from the symposium indicate that genome editing holds great promise for the future of agriculture. However, a balanced approach is necessary—one that considers both its potential benefits and challenges. Scientists, policymakers, and farmers must work together to ensure that gene editing is used responsibly and equitably. With continued research, innovation, and international collaboration, gene editing has the potential to transform agriculture, making it more resilient and sustainable in the face of global challenges.
