"Contributions of Crispr and Gene Editing Technologies to Plant Breeding and Biotechnology: Advances, Integrative Approaches, And Future Directions"

The advent of CRISPR and related gene-editing technologies has revolutionized plant breeding and biotechnology by enabling targeted, efficient, and cost-effective genetic modifications. This review explores the evolution from conventional and molecular breeding to precision genome editing, emphasizing the unique advantages of CRISPR systems, including Cas9, Cas12a, Cas13, base editors, and prime editors. Key methodological aspects such as guide RNA design, delivery strategies, DNA repair pathways, multiplex genome editing, and off-target minimization are discussed in the context of enhancing crop traits. The synergy of CRISPR with complementary biotechnologies—such as seed science, omics platforms, tissue culture, and plant– microbe interaction research—demonstrates its potential to address pressing agricultural challenges including climate resilience, yield improvement, and nutritional enhancement. Comparative insights highlight CRISPR’s superiority over earlier tools like zinc finger nucleases, TALENs, and meganucleases in terms of precision, scalability, and adaptability. Looking forward, innovations in delivery systems, repair engineering, and regulatory frameworks will further shape the trajectory of CRISPR-enabled agriculture, advancing sustainable food production for a growing global population.
