Abstract

AbstractTwenty years have elapsed from the first report of stable transformation of maize. Advances in various free DNA delivery methods and the more recent use of Agrobacterium tumefaciens in maize transformation has led to rapid strides towards increased efficiency and throughput of transgenic plant production. These advances in maize transformation, in conjunction with the discovery of novel genes associated with herbicide resistance and insect tolerance, have led to the widespread adoption of hybrid biotech maize in the commercial marketplace. Since the first commercial release in the 1990s, the past decade has shown that farmers have embraced this technology because of the agronomic, economic and environmental benefits. This chapter highlights the progression of corn biotechnology from its first promise in the form of regeneration of fertile plants from callus cultures in 1975 to global adoption of this technology in 2008.KeywordsTransgenic PlantCallus CultureImmature EmbryoMicroprojectile BombardmentTransgenic Maize PlantThese keywords were added by machine and not by the authors.
