A method of selecting cells from a population of genetically transformed cells into which a desired nucleotide sequence has been introduced. According to the method, in said transformed cells, the desired nucleotide sequence or a jointly introduced nucleotide sequence induces or enhances the positive effect of a compound or a nutrient supplied to the population of cells, thereby allowing identification or identification. selecting transformed cells from untransformed cells, for example, for the preparation of genetically transformed plants not containing as a selection marker a non-native nucleotide sequence encoding resistance to toxins, antibiotics or herbicides. The invention also relates to glucuronide compounds comprising the cytokine glucuronide compounds for use in the method. |
