They may pass various fungi, Agrobacterium species, viruses, and other pathogens to host plants, or from one host plant to another.
She was the first (1977) to demonstrate the presence of a fragment of Agrobacterium Ti plasmid DNA in the nuclear DNA of crown gall tissue.
For agriculture and the environment, landscapes exist to describe the Agrobacterium-mediated transformation of plants, promoters used to regulate gene expression, antibiotic resistance genes and their uses in plant genetic transformation, resistance to Phosphinothricin, positive selection, bioindicators/ambiosensors, and the rice genome.
Transfer DNA (or T-DNA), the transferred DNA of the tumor-inducing (Ti) plasmid of some species of bacteria such as Agrobacterium tumefaciens
