Abstract
- The ability of the plasmid pTF-FC2 to transfer genes into plants was investigated. Using this plasmid as the backbone two plasmids were constructed namely pTD1 and pDER-bar. These plasmids contained, as plant selectable markers, the nptII and the bar genes, respectively. The nptII gene was flanked by the right and left borders and the bar gene was not. Transgenic plants were obtained through the co-cultivation of tobacco leaf discs with the Agrobacterium tumefaciens strain LBA4404(pAL4404)(pDER-bar). Molecular and genetic analysis indicated that the bar gene had been stably integrated into the plant genome and had been inherited in a Mendelian fashion. Integration was shown to be polar and unidirectional and in some cases the entire plasmid was found to have integrated into the plant genome. Interestingly, no plants were generated from tobacco leaf discs that were co-cultivated with the strain C58C1(pMP90)(pTD1). [Copyright &y& Elsevier]
