Different countries have adopted varying approaches to regulate CRISPR-Cas9 applications. For instance, some nations have stringent regulations that limit the use of this technology to specific research contexts, while others have more permissive frameworks that allow broader applications under strict oversight (Shinwari et al., 2018). International cooperation and harmonization of regulatory standards are crucial to ensure the safe and ethical use of CRISPR-Cas9 technology globally. The establishment of comprehensive legislation that balances scientific freedom with ethical considerations is essential for the responsible advancement of genome editing technologies (Memi et al., 2018). 7.3 Public perception and acceptance Public perception and acceptance of CRISPR-Cas9 technology play a critical role in its development and application (Zhou et al., 2024). There is a need for transparent communication and public engagement to address the ethical, moral, and safety concerns associated with genome editing. Public awareness campaigns and educational initiatives can help demystify the technology and foster informed discussions about its potential benefits and risks. Engaging with various stakeholders, including ethicists, policymakers, religious scholars, and the general public, is essential to build trust and ensure that the societal implications of CRISPR-Cas9 are thoroughly considered. Public acceptance is likely to be influenced by the perceived benefits of the technology, such as its potential to treat genetic diseases and improve agricultural productivity, as well as the robustness of regulatory frameworks in place to mitigate risks (Ayanoğlu et al., 2020). In conclusion, while CRISPR-Cas9 technology holds immense promise, addressing the ethical and regulatory challenges is crucial for its responsible and sustainable development. A balanced approach that considers ethical issues, establishes robust regulatory frameworks, and engages the public will be key to harnessing the full potential of this revolutionary technology (Eş et al., 2019). 8 Future Directions and Potential Applications 8.1 Emerging trends in genome editing The CRISPR-Cas9 technology has revolutionized genome editing, and recent advancements continue to expand its capabilities. Emerging trends include the development of more precise gene editing techniques such as base editing and prime editing, which allow for targeted nucleotide changes without inducing double-strand breaks (Zhu et al., 2020). These advancements are crucial for minimizing off-target effects and increasing the specificity of genome edits. Additionally, novel CRISPR variants like xCas9 and Cas12a (Cpf1) have been engineered to overcome PAM restrictions and improve editing efficiency. The integration of CRISPR with other biotechnologies, such as RNA interference and transcription activator-like effector nucleases (TALENs), further enhances its versatility and application scope (Eş et al., 2019)。 8.2 Novel applications in Bt research In the context of Bacillus thuringiensis (Bt) research, CRISPR-Cas9 technology offers promising avenues for functional studies and genetic modifications. The ability to create targeted gene knockouts and insertions can help elucidate the roles of specific genes in Bt's pathogenicity and environmental interactions (Bishnoi, 2023). Moreover, CRISPR can be employed to engineer Bt strains with enhanced insecticidal properties or broader host ranges, thereby improving their efficacy as biopesticides. The development of multiplexed gene editing techniques allows for simultaneous modifications of multiple genes, facilitating comprehensive functional analyses and the creation of Bt strains with complex trait improvements (Huang and Puchta, 2021). 8.3 Potential for industrial and agricultural biotechnology The potential applications of CRISPR-Cas9 in industrial and agricultural biotechnology are vast. In agriculture, CRISPR can be used to develop crop varieties with improved yield, quality, and resistance to diseases and environmental stresses. For instance, CRISPR-edited crops with enhanced nutritional profiles or reduced allergenicity are already being explored. In industrial biotechnology, CRISPR can be utilized to optimize
