CRISPR-Cas9: A Tool Used in Plant Breeding

Abstract

CRISPR-Cas9, a revolutionary tool for genome editing, has significantly impacted plant breeding by allowing precise genetic modifications with exceptional efficiency and accuracy. This review explores the applications, mechanisms, and implications of CRISPR-Cas9 technology in plant breeding. It outlines the molecular principles of the CRISPR-Cas9 system, focusing on its ability to target specific genes and introduce traits like disease resistance, enhanced yield, and better resilience to environmental stresses. The review highlights the advantages of CRISPR-Cas9 over traditional breeding methods, such as its speed, cost-effectiveness, and precision. Additionally, it addresses the challenges and regulatory issues surrounding its use in agriculture, including off-target effects, ethical concerns, and regulatory frameworks. The review concludes by considering the future potential of CRISPR-Cas9 in fostering sustainable agricultural practices and its role in ensuring global food security in the face of climate change and population growth.
