[T-DNA integration patterns in transgenic plants mediated by Agrobacterium tumefaciens]

The genetic transformation mediated by Agrobacterium tumefaciens has been widely applied to research of transgenic plants. As the vector of the exotic genes, the integration patterns of T-DNA fragments affects not only transformation efficiency and stability, but also expression properties of the transgenes. This review summaries the two major patterns and the rules of T-DNA integration in Agrobacterim-mediated transformation, rules of T-DNA mediated by Agrobacterium tumefaciens, as well as research tools for flanking sequence amplification. It is attempted to provide references for researches on transformation and T-DNA integration mutation mediated by Agrobacterium tumefaciens.
