Popis: Conjugative transfer of a broad-host range plasmid and transformation-mediated transfer of chromosomal genes were found to occur at significant frequencies between Ralstonia solanacearum and Acinetobacter sp. in planta. These intergeneric gene transfers are related to the conditions provided by the infected plant, including the extensive multiplication of these two bacteria in planta and the development of a competence state in Acinetobacter sp. Although interkingdom DNA transfer from nuclear transgenic plants to these bacteria was not detectable, plants infected by pathogens (e.g., Ralstonia solanacearum) and co-colonized by soil saprophyte bacteria (e.g., Acinetobacter sp.) can be considered as potential “hot spots” for gene transfer, even between phylogenetically remote organisms.
