Global agricultural production is significantly reduced by abiotic stressors such as drought, salinity, cold, heat, and heavy metals. To deal with these environmental pressures, techniques like transgenic and conventional breeding have been applied extensively. Because of its ease of use, accessibility, versatility, adaptability, and broad range of applications, the clustered regularly interspaced short palindromic repeat-Cas (CRISPR/Cas) based gene editing technology has revolutionized. The development of crop varieties with improved resistance to abiotic stressors is a promising use of this technology. In order to improve tolerance to stresses like as drought, salinity, cold, heat, and heavy metals, we have applied the CRISPR/Cas mediated gene-editing system. Here, we provide an overview of the most recent research on this topic. Additionally, we emphasized in this review the most current developments in base and prime editing tools for crop enhancement.
