A method of selecting genetically transformed cells from a population of cells comprising introducing a desired nucleotide sequence and a co-introduced nucleotide sequence into the genome of a cell whereby the desired nucleotide sequence or the co-introduced nucletoide sequence induces a positive effect by giving the transformed cells a competitive advantage when the population of cells are supplied with an inactive compound thereby allowing the transformed cells to be identified and selected from the non-transformed cells by means defined as positive selection; as well as cells transformed according to the method and plants derived therefrom. The invention further relates to novel glucuronide compounds including cytokinin glucuronide compounds for use in the method.

Positive selection
