CRISPR/Cas-Mediated Multiplex Gene Editing in Tomato (Solanum Lycopersicum L.)

By 2050, the implementation of genome-editing tools to alter plant procreation may enhance food supply sustainably. As a result of more lenient regulatory frameworks and a broader societal acceptance of genome editing, products made possible through these technologies are becoming more widely recognised and appreciated. Under the farming methods used today, population worldwide and availability of food would never have increased in proportion. The tomato (Solanum lycopersicum), a vegetable crop, represents one of the most prominent and widely utilised crops in the world. Addressing the complex genetic and biochemical makeup of fruit quality represents a remarkable challenge in the implementation of genome-editing technologies. However, on-going research and advancements in understanding fruit biology and genetics are gradually opening up opportunities for targeted improvements in fruit quality attributes. In recent years, due to its efficiency, high target precision, and versatility, CRISPR/Cas9 has been recognised as one of the most intriguing approaches for knocking out disease susceptibility genes in a variety of simulation and crop plants to create tolerance/resistance to a wide range of plant diseases. There have been reports of using the CRISPR/Cas9 system for this specific purpose, even if various techniques, like as RNAi, have been used to knock down these two S genes in order to give resistance in tomato against Fusarium wilt. In summary, this review provides a comprehensive overview of the mechanism and optimisation of the CRISPR system, as well as its versatile applications in tomato. It underscores the potential of CRISPR technology to enhance tomato crop resilience, quality, and domestication, while emphasising the importance of ethical and regulatory considerations in its implementation.
