Agriculture, the foundation of human civilization, has witnessed significant transformations over the centuries (Thrall et al., 2010). These advancements, particularly in modern times, have been driven by the need to address issues like food security, environmental sustainability, and the pressures posed by a rapidly growing global population (Bahar et al., 2020; Wani et al., 2023). Among the most transformative breakthroughs in recent decades is genetic engineering, which integrates molecular biology with plant science to create innovative agricultural solutions. By enabling precise modifications to plant genomes, genetic engineering offers the potential to solve some of the most pressing challenges in food production and sustainability (Yuan et al., 2024; Aziz and Masmoudi, 2025). In this editorial, it is examined how genetic engineering bridges plant science and molecular biology to create sustainable solutions for agriculture, exploring its impact on crop productivity, resilience, and food security.
Plant science studies plant biology, growth, development, and interactions with the environment to improve crop yields, nutritional value, and resilience to diseases and environmental stresses (Kim et al., 2021; Guzmán et al., 2022). Molecular biology focuses on understanding molecular mechanisms within cells, including gene expression, protein synthesis, and DNA replication, to gain insights into how organisms function at the genetic level (Yang et al., 2024). Genetic engineering in agriculture merges these two fields by using molecular biology tools to alter the genetic makeup of plants, introducing new traits that are beneficial for farming (Dong and Ronald, 2019). Unlike traditional breeding techniques, which rely on cross-breeding plants with desirable traits, genetic engineering enables more precise and targeted changes to an organism's genome. Through this process, specific genes can be inserted, deleted, or modified to enhance certain characteristics, such as pest resistance, drought tolerance, or improved nutritional content (Gao, 2021; Ahmad, 2023; Dutta, 2024a, 2024b).
The world’s population is expected to reach 9.7 billion by 2050, putting immense pressure on global food production systems. According to the Food and Agriculture Organization (FAO), agricultural production must increase by 70% to meet this demand (Daszkiewicz, 2022). This challenge is compounded by environmental factors such as climate change, water scarcity, and soil degradation, which are threatening the viability of traditional farming practices (da Gama, 2023). In this context, genetic engineering offers a powerful solution to increase crop productivity and ensure food security. Traditional methods of improving crops are often slow, labor-intensive, and limited by natural genetic variation. Genetic engineering, however, allows scientists to introduce traits that enhance crop performance, making it a crucial tool for addressing global food security challenges (Anjanappa and Gruissem, 2021; Patil et al., 2025). By integrating molecular biology into plant science, genetic engineering offers a faster, more efficient means of developing crops that can thrive in increasingly difficult environmental conditions while providing higher yields and improved nutritional value (Aziz et al., 2022; Wang and Demirer, 2023).
One of the most significant advantages of genetic engineering is its ability to enhance crop resilience to environmental stressors, such as drought, extreme temperatures, and soil salinity. In many regions of the world, water scarcity and changing weather patterns pose a direct threat to crop production. Traditional crops are often ill-suited to cope with these conditions, leading to poor yields and food shortages (Shelake et al., 2022; Muhammad et al., 2024). Genetic engineering allows the introduction of genes from drought-resistant plants to help crops endure water stress. For example, GM rice and maize varieties are designed to thrive in flood-prone and arid areas, reducing water usage and promoting conservation (Valliyodan et al., 2016; Villalobos-López et al., 2022). Genetic engineering has produced crops that tolerate extreme temperatures and saline soils, enabling growth in previously unsuitable areas and enhancing food security while reducing land conversion and deforestation (Gill et al., 2014; Tarolli et al., 2024).
The widespread use of chemical pesticides has raised concerns about environmental pollution and health risks, while genetic engineering has led to the development of pest-resistant crops, reducing the need for chemical pesticides (Ahmad et al., 2024; Kaur et al., 2024). Bt (Bacillus thuringiensis) crops are genetically engineered to produce a protein toxic to specific insect pests but safe for humans, animals, and beneficial insects. For instance, Bt cotton protects against the cotton bollworm, reducing the need for chemical insecticides and minimizing environmental damage while improving crop health (Abu El-Ghiet et al., 2023). In addition to pest resistance, genetic engineering can also be used to create crops that are resistant to diseases caused by fungi, viruses, and bacteria. The ability to reduce pesticide use through genetic modifications leads to a more sustainable agricultural system, which benefits both farmers and the environment (Dong and Ronald, 2019; van Esse et al., 2020).
Malnutrition is a global issue, especially in developing countries with nutrient-deficient diets. Genetic engineering, through biofortification, can enhance the nutrient content of staple crops, showing promise in improving global health (Mmbando and Missanga, 2024; Naik et al., 2024). Golden Rice is a genetically engineered crop designed to produce higher levels of provitamin A (beta-carotene), addressing vitamin A deficiency, a leading cause of blindness and health issues in developing countries. Its introduction could save millions of lives by improving vitamin A intake in regions with limited access to other nutrient sources (Tang et al., 2009; Dubock, 2017). Other crops have also been genetically engineered to enhance essential amino acids, iron, and zinc content, addressing widespread nutrient deficiencies. This approach offers a powerful tool to combat malnutrition, especially in regions with limited agricultural productivity and restricted access to diverse food sources (Sandhu et al., 2023; Naik et al., 2024)
Genetic engineering in agriculture can promote sustainable farming by reducing the need for chemical fertilizers and pesticides, conserving water, and optimizing land use. Crops engineered to require fewer inputs are more environmentally friendly and cost-effective for farmers (Das et al., 2023; Gamage et al., 2024). For example, nitrogen-efficient crops are being developed to reduce the need for synthetic fertilizers, which contribute to pollution and greenhouse gas emissions. Similarly, pest- and disease-resistant genetically engineered crops can lower pesticide use, reducing the environmental impact of farming (Brunelle et al., 2024). Crops with improved nutrient content and higher yields can reduce food waste by enabling farmers to grow more food on less land, conserving natural resources. Incorporating genetic engineering into agriculture promotes sustainability by increasing productivity while minimizing the negative impacts of conventional farming (Aziz et al., 2022; Zuma et al., 2023).
While genetic engineering in agriculture offers significant benefits, it also raises ethical and environmental concerns. Critics worry about unintended consequences, such as gene flow to wild relatives, the development of resistant pests, and the long-term impact on biodiversity (Idris et al., 2023). Public perception of genetic engineering remains divided, with some people expressing concerns about the safety of GMOs and the potential for corporate control over agricultural systems. Transparency in research, strict regulatory oversight, and open dialogue between scientists, policymakers, and the public are crucial to addressing these concerns (Lucht, 2015; Dessie and Zegeye, 2024).
Ethical considerations regarding the patenting of genetically modified seeds and the monopolization of agricultural technology by large corporations must be addressed. The benefits of genetic engineering should be equitably distributed to ensure smallholder farmers and developing countries also have access to these innovations (Aziz et al., 2022; Idris et al., 2023).
Genetic engineering in agriculture offers a transformative solution to food security, environmental sustainability, and global malnutrition. By combining plant science and molecular biology, it enables the creation of crops that are more resilient, nutritious, and less reliant on harmful chemicals. While the benefits are significant, addressing ethical concerns and public perceptions is essential for responsible and equitable use, ensuring a sustainable, food-secure future.
