Genetic Engineering and Its Applications in Modern Agriculture

Abstract

Genetic engineering has become an important component of modern agricultural biotechnology, allowing researchers to introduce, modify, silence, or precisely alter genes associated with desirable plant and animal traits. Agricultural genetic engineering has been used to develop crops with resistance to insects and diseases, tolerance to selected environmental stresses, improved nutritional characteristics, and changes in agronomic performance. Modern genome-editing technologies, particularly CRISPR-based systems, have expanded these possibilities by enabling targeted modifications without necessarily introducing foreign DNA.  This paper examines nine major applications of genetic engineering in agriculture, including crop improvement, pest resistance, herbicide tolerance, disease resistance, nutritional enhancement, abiotic-stress tolerance, genome editing, livestock biotechnology, and sustainability. It also considers biosafety, regulation, public acceptance, and future directions in agricultural biotechnology.
