Abstract
Expression of introduced genes in transgenic plants varies between individual regenerants. Horsch et al. (1985) assumed influences of the surrounding DNA or the chromatin structure at the insertion site on the foreign genes and called this phenomenon “position effect”. Integration of the introduced genes via Agrobacterium into the plant genome occurs randomly. The number of integrated gene copies cannot be influenced at the time of transformation. These uncertainties hamper the predictability of transformation results (Deroles and Gardner 1988a,b; Dunwell and Paul 1990).
