Unlocking the green revolution CRISPR-cas9 and the future of sustainable plant breeding: A review
Article Main
Abstract
Agriculture underwent significant changes with the Green Revolution, which substantially increased food production; however, with the global population projected to reach 11.2 billion by 2050, the demand for food is expected to continue rising. Researchers are employing novel technologies, such as Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) and CRISPR-associated protein 9 (CRISPR-Cas9) genome editing, to address this issue. The information is gathered using keywords such as "green revolution," "CRISPR-Cas9," "sustainable agriculture," "gene editing," and "crop improvement" from authenticated sources, including Google Scholar, PubMed, and NCBI. This review explores the potential of CRISPR-Cas9 to unlock new possibilities for crop improvement, with a focus on enhancing resistance to pests and diseases. Creating crops with inbuilt defenses could reduce chemical pesticide use, improving environmental and human health. Increased stress tolerance can be achieved by genetically altering crops to resist heat, salt, drought, and other environmental challenges, thereby ensuring food security. CRISPR-Cas9 also enables biofortification, enhancing crops with essential vitamins and minerals, thereby addressing dietary inadequacies and malnutrition. Introducing genes that enable nitrogen fixation within crops may reduce reliance on synthetic fertilizers, promoting environmentally friendly farming. The application of CRISPR-Cas9 in agriculture is also subject to regulatory frameworks, potential unexpected consequences, and ethical considerations, all of which require careful evaluation. This review highlights these aspects, emphasizing that responsible research and development are essential for the ethical and long-term use of this technology. It attempts to illustrate the transformative capability of this technology for creating a more sustainable and food-secure future by critically assessing its possibilities and challenges.
