Abstract:
To develop an Agrobacterium mediated transformation protocol for chrysanthemum we studied the transformation efficiency of commonly used A.tumefaciens strains on 14 genotypes by comparing tumour size and frequency. One genotype was analyzed in detail using 14 strains of both A.tumefaciens and A.rhizogenes. Only a few genotype/strain combinations resulted in significant tumour formation. Especially 0-type strains were highly efficient. An 0-type strain was used to transfer genes for neomycine phosphotransferase (NPT II) and ß-glucuronidase (GUS) to a susceptible cultivar. Transfer of the GUS gene was confirmed by using the Polymerase Chain Reaction (PCR).

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...
Bacterial Transformation
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...
