Abstract:
This chapter describes a rapid and efficient protocol for explant preparation and genetic transformation of carnation. Node explants from greenhouse-grown plants and leaf explants from in vitro plants are infected with Agrobacterium tumefaciens AGL0 harboring pKT3 plasmid, consisting of GUS and NPTII genes. Explant preparation is an important factor to obtain the transformed plants. The GUS-staining area was located only on the cut end of explants and only explants with a cut end close to the connecting area between node and leaf, produced transformed shoots. The cocultivation medium is also an important factor for the successful genetic transformation of carnation node and leaf explants. High genetic transformation efficiency of node and leaf explants cocultured with Agrobacterium tumefaciens was achieved when the explants were cocultivated on a filter paper soaked with water or water and acetosyringone mixture (AS).

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...
