The instant invention provides a method for the selection of transformed plant cells, comprising the steps of: i) transforming plant cells with a polynucleotide sequence comprising a plant expressible gene encoding a tryptophan analogue converting activity, ii) culturing said plant cells, or growing plant material comprising said plant cells, in the presence of a selective amount of a tryptophan analogue deleterious to non-transformed plant cells, under conditions that allow for the manifestation of said deleterious effect. |
