For instance, the optimization of CRISPR/Cas9 systems for specific crops, such as kiwifruit, benefits from collaborative efforts that bring together diverse scientific perspectives and methodologies. Such collaborations also facilitate the exchange of knowledge and technology, which is essential for the global advancement of agricultural biotechnology (Ho et al., 2020). 7.3 Necessity of building an open-access kiwifruit genetic resource database An open-access kiwifruit genetic resource database is essential for supporting ongoing research and development efforts. This database would serve as a centralized repository for genetic information, including gene sequences and phenotypic data, which are critical for CRISPR/Cas9-mediated trait improvement (Arora and Narula, 2017). By providing researchers with easy access to comprehensive genetic resources, such a database would enhance the efficiency of breeding programs and enable more precise gene-editing interventions. It would also promote transparency and reproducibility in research, fostering a collaborative scientific community (Huang, 2024). 8 Concluding Remarks CRISPR/Cas9 technology has significantly advanced the genetic improvement of kiwifruit by enabling precise genome editing. This technology has been successfully applied to modify key genes associated with important traits such as disease resistance, plant architecture, and fruit quality. For instance, the use of CRISPR/Cas9 has led to the development of kiwifruit with reduced susceptibility to diseases and improved fruit yield and quality. The optimization of CRISPR/Cas9 systems, such as the paired-sgRNA/Cas9 system, has further enhanced editing efficiency, allowing for more effective trait improvement in kiwifruit. The future of gene-editing research in kiwifruit looks promising, with potential advancements in transgene-free genome editing and the de novo domestication of wild relatives. These approaches could lead to the development of new kiwifruit cultivars with enhanced traits such as increased resistance to environmental stressors and improved nutritional content. Additionally, the integration of CRISPR/Cas9 with other emerging technologies, such as base editing, could further expand the scope of genetic modifications possible in kiwifruit. Future breeding strategies may focus on multiplex genome editing to simultaneously target multiple traits, thereby accelerating the development of superior kiwifruit varieties. This study underscores the transformative impact of CRISPR/Cas9 technology on the genetic improvement of kiwifruit, offering a powerful tool for addressing key challenges in kiwifruit cultivation. By enabling precise and efficient genetic modifications, CRISPR/Cas9 facilitates the development of kiwifruit varieties with enhanced agronomic traits, which can lead to increased productivity and economic benefits for the kiwifruit industry. The advancements in gene-editing techniques also hold the potential to improve the sustainability of kiwifruit production by reducing reliance on chemical inputs and enhancing resilience to climate change. Overall, this study highlights the critical role of CRISPR/Cas9 in driving innovation and growth in the kiwifruit sector.
