Delivery Systems for Plant Genome Editing Technology
摘要
Plant genetic engineeringGenetic engineering has revolutionized modern agriculture by providing opportunities to develop crops with enhanced characteristics such as disease resistance, abiotic stressAbiotic stress tolerance, improved nutritional value, and increased yield. Agrobacterium-mediated transformation, one of the most widely used methods for introducing foreign DNA into plant genomes, offers high efficiency, stable integration of foreign DNADNA, and the ability to transfer large DNA fragments. However, it also has limitations, including the potential for insertional mutagenesisMutagenesis and a limited host range. To overcome these issues, researchers have developed non-Agrobacterium-based delivery systemsNon-Agrobacterium-based delivery systems, which include viral vectors, physical methods, and chemical methods. These alternative systems provide several advantages, such as a rapid transformation process, no species limitation, and ease of use with less specialized equipment. The advent of genome editingGenome editing technology has raised ethical and safety concerns. Ethical issues involve the control and ownership of genetically modified organisms, potential unintended consequences, and social inequality. Safety concerns focus on off-target effects, unintended mutations, and the spread of genetically modified organismsGenetically modified organisms (GMO) into the environment. Viral-based delivery systems, in particular, have the potential to spread beyond the intended target organism and potentially infect other organisms, including humans. Physical and chemical delivery systemsChemical delivery system also carry risks of off-target effects and unintended mutations, highlighting the need for careful consideration and regulation in the use of these technologies.
