Summary Introduction
Introduction:
Transgenic plants are those plants which are genetically modified or engineered by using the recombinant DNA (deoxyribonucleic acid) technique for the formation of plants having desiring characteristics. They are also referred to as the genetically modified organisms or GMOs.
