Genetically by Modified Crops: An Overview

Navin Srivastava, Vijai Kumar Gupta, Rajesh Pati and Rajarshi Kumar Gaur

Biotechnology, 2011, 10(2), 136-148.


Genetically modified transgenic crops also referred to as a Genetically Modified (GM) crops are produced by when the genetic material of an organism (either DNA or RNA) is altered by use of recombinant DNA technology and the modification can be replicated and/or transferred to other cells or organisms. The recently understood recombinant DNA technology has potential, via genetic engineering, to incorporate a specific gene which controls a particular trait, without co-transfer of undesirable genes from donor species as occurs in conventional breeding. In recent year, the globally cultivated area of transgenics crops has increased more than 81 million hectares. Most GM crops grown today have been developed to resist certain insect pests. There are GM plants being developed today to produce specific vitamins, resist plant viruses and even produce products for medicinal uses.
