Transgenic potato plants with the nptII gene coding for neomycin phosphotransferase
(kanamycin resistance) as a selection marker were examined for the spread of recombinant …

The nptII+ gene present in the genome of transgenic potato plants transforms naturally
competent cells of the soil bacteria Pseudomonas stutzeri and Acinetobacter BD413 (both …

The use of genetically engineered crop plants has raised concerns about the transfer of their
engineered DNA to indigenous microbes in soil. We have evaluated possible horizontal …

We have developed a novel system for the sensitive detection of nptII genes (kanamycin
resistance determinants) including those present in transgenic plant genomes. The assay is …

Previous studies had shown that recombinant DNA can be detected for several months in
soil after the deposition of litter from transgenic (tg) plants. Here we show by PCR monitoring …

The persistence of transgenic Agrobacterium tumefaciens was investigated in field releases
of transgenic sugarbeet and potato plants in Germany in 1993 and 1994. Leaf material …

The likelihood of gene transfer from transgenic plants to bacteria is dependent on gene
number and the presence of homologous sequences. The large number of transgene copies …

An Agrobacterium-mediated transformation system has been developed for introducing
foreign genes into the three most important potato cultivars in New Zealand ('Ilam …

Here we show that horizontal transfer of DNA, extracted from transgenic sugar beets, to
bacteria, based on homologous recombination, can occur in soil. Restoration of a 317-bp …

Agrobacterium-mediated genetic transformation is a method of choice for the development
of transgenic plants. The presence of latent Agrobacterium that multiplies in the plant tissue …
