Agrobacterium T-DNA integration: molecules and models.
Genetic transformation mediated by Agrobacterium involves the transfer of a DNA molecule (T-DNA) from the bacterium to the eukaryotic host cell, and its integration into the host genome. Whereas extensive work has revealed the biological mechanisms governing the production, Agrobacterium-to-plant cell transport and nuclear import of the Agrobacterium T-DNA, the integration step remains largely unexplored, although several different T-DNA integration mechanisms have been suggested. Recent genetic and functional studies have revealed the importance of host proteins involved in DNA repair and maintenance for T-DNA integration. In this article, we review our understanding of the specific function of these proteins and propose a detailed model for integration.
