A method for transformation of sugar beet protoplasts includes obtaining protoplasts from stomatal guard cells isolated from a sugar beet plant. The protoplasts are transformed with a nucleic acid construct including a nucleotide sequence of interest and Transcription Activator-Like Effector Nucleases (TALEN) or one or more vectors including sequences encoding these Transcription Activator-Like Effector Nucleases (TALEN)sequences. The TALEN target and process a target sequence and replace the target sequence through homologous recombination with the nucleic acid construct including the nucleotide sequence of interest, -possibly applying to an in vitroculture of the protoplasts, a medium that is toxic, preferably lethal to the in vitroculture of the protoplasts. Sugar beet plants are regenerated from the cell culture, preferably from the surviving protoplasts having integrated the nucleic acid construct including the sequence of interest that possibly renders the transformed cell resistant to the toxic activity of the applied medium. |
