Higher Plant Vector Systems

Higher plant transformation vector systems are mainly developed based on the natural biosystems which infecting higher plants. Two major groups attracting much of the research are Cauliflower mosaic virus and Agrobacterium tumefaciens. Cauliflower mosaic virus has a double stranded genome, and a portion of the genome can be substituted for a foreign DNA segment without loosing the ability of infection. A. tumefaciens carries a large plasmid. Ti plasmid whose portion can be substitute and trasferred into the plant chromosome.
