Abstract
Genetically modified (GM) and gene-edited (GE) food crops have emerged as transformative technologies in agriculture, offering potential solutions to address global food security challenges. This chapter overviews the current status and future prospects of genetically modified and gene-edited food crops, highlighting their existing applications and potential impacts on agriculture and society. Genetically modified crops involve intentionally changing an organism's genome by introducing foreign genes, which enable desired traits such as resistance to pests, diseases, or environmental stresses. Gene editing technologies, such as clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein 9 (Cas9), transcription activator-like effector nucleases (TALENs), zinc-finger nucleases (ZFNs), etc., have become a precise and efficient tool for targeted genetic modifications. Unlike traditional genetic modification, gene editing allows for precise alterations within an organism's genome without introducing foreign DNA. This technology has opened up new possibilities for crop improvement, including enhanced disease resistance, improved nutritional content, and increased tolerance to adverse growing conditions. Gene-edited crops hold significant promise for sustainable agriculture, with potential benefits including reduced chemical inputs, increased crop adaptability, and improved crop quality. The regulatory landscape surrounding genetically modified and gene-edited crops varies across countries, with some nations implementing strict regulations while others adopt a more permissive approach. Nevertheless, the future prospects of genetically modified and gene-edited food crops appear promising. Continued advancements in gene editing technologies, coupled with ongoing research on the safety and efficacy of these crops, will contribute to their further adoption and acceptance. However, careful monitoring of potential environmental impacts, addressing public concerns, and transparent communication about the benefits and risks of these technologies will be crucial to their successful integration into global agriculture.
