Abstract
The present invention relates to an improved process for transforming plant protoplasts using simple, purely chemical, process steps, and to the plant material obtainable by this method. The transfer of the genetic material into the plant cell is carried out directly, without the use of a natural plant-infective system such as a plant bacterium or plant virus, and without transfer by insects or phytopathogenic fungi, by joint incubation in a suitable incubation medium of the DNA to be transformed and plant protoplasts. In this manner, desired genes can very simply and efficiently be transferred to plant material, resulting in plants with improved properties.
