Abstract

Agrobacterium tumefaciens and its related species, A. rhizogenes and A. vitis, are the only known bacterial pathogens which ‘genetically invade’ host plants and stably integrate part of their genetic material into the host cell genome. Thus, A. tumefaciens has evolved as a major tool for plant genetic engineering. Furthermore, this unique process of interkingdom DNA transfer has been utilized as a model system for studies of its underlying biological events, such as intercellular signalling, cell-to-cell DNA transport, protein and DNA nuclear import and integration. To date, numerous bacterial proteins and several plant proteins have been implicated in the A. tumefaciens–plant cell interaction. Here, we discuss the molecular interactions among these bacterial and plant factors and their role in the A. tumefaciens–plant cell DNA transfer.
