Acquisition of an oncogenic tumor-inducing (Ti) or root-inducing (Ri) plasmid by soil-dwelling agrobacteria confers pathogenic characteristics. With the ability to transfer plasmids into plants ...

Agrobacterium tumefaciens is a plant pathogen responsible ... and use their type IV secretion system to inject the plant cells with T-DNA, produced by the Ti plasmid, and other virulence proteins.

Alternatives to Agrobacterium may circumvent patents on ... on a family of giant extrachromosomal circular plasmids called Ti (Tumor-inducing) plasmids. Virulence genes deliver a specific part ...

Studies to date have suggested that Osa blocks T-DNA and VirE2 transfer from Agrobacterium to the plant ... Osa degrades Ti plasmid-encoded T-DNA in the T-DNA:VirD2 complex before its ...

Initially, the agrobacterium cell contains a bacterial chromosome and a Tumor-inducing plasmid (Ti plasmid). The Ti plasmid is removed from the agrobacterium cell, and a restriction enzyme cleaves the ...
