Abstract: The stability of the inserted transgenes and particularly the junction regions of transgenic events is a concern of food labeling, traceability and post release monitoring, as these regions are used for development of event-specific DNA-based detection methods. During the standard agricultural breeding practices, the transgenic lines can be exposed to completely different conditions than those in the laboratory environment. Some of these conditions have the potential to affect the stability of the transgenic locus and the surrounding DNA. As tissue culture is recognized as a stressful and mutagenic factor, we have analyzed the effect of this process on the stability of the junction regions at nucleotide level in five Arabidopsis thaliana transgenic lines in comparison with the respective integration loci in ColO and C24 ecotypes. No indication of any kind of alteration at nucleotide level of the junctions was found. The relevance of the stability of the plant-T-DNA junction regions for application of the DNA-based methods in commercial transgenic plants is discussed.
