Abstract:
Biolistic gun-mediated transformation is one of the two most effective and popular methods for introducing genes into maize. In this chapter, we describe a detailed protocol for genetic transformation of the maize genotype, Hi II. The protocol uses 0.6-microm gold particles as microcarriers and the herbicide resistance bar gene as a selective marker. Both immature zygotic embryos and immature embryo-derived callus cultures can be transformed using this protocol. To ensure successful reproduction of this protocol, we provide step-by-step laboratory transformation procedures as well as details on growing and caring for transgenic plants in the greenhouse.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
