ABSTRACT CRISPR technologies are rapidly transforming agriculture by enabling precise and programmable modifications across a wide range of organisms. This review provides an overview of CRISPR applications in crops, livestock, aquaculture, and microbial systems, highlighting key advances in sustainable agriculture. In crops, CRISPR has accelerated the improvement of traits such as drought tolerance, nutrient efficiency, and pathogen resistance. In livestock and aquaculture, CRISPR has enabled disease‐resistant pigs and poultry, hornless cattle, and fast‐growing, stress‐tolerant fish. Engineered microbes are also being leveraged to enhance nitrogen fixation and reduce input reliance. We examine the evolution of CRISPR tools, such as base and prime editing, multiplex editing, and epigenome modulation, that expand precision and control beyond traditional gene knockouts. These innovations offer significant advantages over conventional breeding, yet challenges remain, including off‐target effects, delivery efficiency, and regulatory variability across countries. The review also explores emerging directions such as novel Cas variants and AI‐integrated breeding platforms for high‐throughput trait discovery. Together, these developments demonstrate the transformative potential of CRISPR technology to reshape agriculture, not only by enhancing productivity and resilience but also by reducing environmental impacts. With responsible implementation, CRISPR‐enabled innovations are well‐positioned to support global food security and sustainability targets by 2050.
