Large plasmid in Agrobacterium tumefaciens essential for crown gall-inducing ability

THE gram-negative bacterium Agrobacterium tumefaciens induces crown gall tumours in many, mostly dicotyledonous, plants. Zaenen et al. 1 demonstrated the presence of one or more large plasmids in a number of crown gall-inducing Agrobacterium strains belonging to seven different Agrobacterium groups....

Description
Summary:THE gram-negative bacterium Agrobacterium tumefaciens induces crown gall tumours in many, mostly dicotyledonous, plants. Zaenen et al. 1 demonstrated the presence of one or more large plasmids in a number of crown gall-inducing Agrobacterium strains belonging to seven different Agrobacterium groups. They were not able to find such plasmids in eight non-pathogenic Agrobacterium strains belonging to four of the same groups 2,3 . They therefore formulated the hypothesis that the genetic information for the tumour-inducing principle 4 in crown gall-inducing Agrobacterium strains is carried by one or several large plasmids.
