Patent ID: 7989678

Claim:
A method for producing a transgenic plant cell or a transgenic plant, comprising: a) providing bacteria of a transgenic non-pathogenic strain variant of Agrobacterium strain K599 (NCPPB 2659) which comprise a genome comprising a 16S-23S rRNA intergenic sequence comprising at least one sequence motif selected from the group consisting of SEQ ID NO:5, 6, 7, 8, 9, 10, 11, 12, 13, and 14, wherein said strain variant is capable to infect plant cells, to mediate T-DNA transfer into plant cells, and to mediate T-DNA insertion into the plant genome, but is lacking hairy root phenotype inducing properties, and wherein said strain variant further comprises a transgenic T-DNA, b) co-cultivating a plant, plant cell or plant tissue with said bacteria, and c) isolating or selecting plant cells comprising stably integrated into their genome said transgenic T-DNA, and optionally d) regenerating plants comprising stably integrated into their genome said transgenic T-DNA.
