Informations supplémentaires
The left border (LB) and right border (RB) of the Ti plasmid (tumour-inducing plasmid) are the signals that flank the T-DNA (transferred DNA) which is introduced into the plant genome upon being infected by the soil bacterium Agrobacterium tumefaciens.

When used in modern biotechnology for the development of LMOs, the virulent genes naturally occurring in Agrobacterium tumefaciens between the LB and RB are replaced by a DNA cassette containing the gene(s) of interest. Therefore, when a plant is transformed using Agrobacterium tumefaciens, the T-DNA containing the cassette with gene(s) of interest is integrated into the plant's genome.
