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.
一种从细胞群中选择
基因转化细胞的方法,包括将所需的核苷酸序列和共同引入的核苷酸序列引入细胞的
基因组中,从而使得所需的核苷酸序列或共同引入的核苷酸序列在细胞群被提供非活性化合物时诱导产生积极效应,从而使得转化的细胞在正向选择的定义下具有竞争优势,从而可以从未转化的细胞中确定和选择出转化的细胞;以及根据该方法转化的细胞和由此派生的植物。该发明还涉及包括
细胞分裂素葡萄糖醛酸化合物在内的新型
葡萄糖醛酸化合物,用于该方法。
