Abstract

The phenomenon of global climate change poses a significant threat to global food security, primarily due to the limited adaptability of major staple crops and plant species to the changing climatic conditions. This poses a significant challenge for farmers, agricultural experts, and policymakers worldwide as they seek to develop sustainable solutions to ensure adequate food supply in the face of climate changeinduced threats. Significant improvement has been made to preserve crop yield, employing traditional breeding methods and cutting-edge molecular techniques to enhance the procedure. The utilization of CRISPR/Cas technology has recently gained traction as a viable alternative to transgenic methods in plant breeding. Our study in this chapter, for the first time, delves into the advantages of the CRISPR/Cas system in plant physiology, exploring key areas such as its impact on environmental factors, the underlying mechanisms of the CRISPR/Cas system, enhanced quality and yield, mitigation of biotic and abiotic stresses, ethical considerations, and regulatory issues, as well as the future prospects of this method.
