The invention relates to methods for stably integrating a desired polynucleotide into a plant genome, comprising transforming plant material with a first vector comprising nucleotide sequences encoding TAL proteins designed to recognize a target sequence transforming the plant material with a second vector comprising (i) a marker gene that is not operably linked to a promoter ("promoter-free marker cassette") and which comprises a sequence homologous to the target sequence and (ii) a desired polynucleotide and identifying transformed plant material in which the desired polynucleotide is stably integrated.
