Abstract
A total of 20 laboratory substrains of Agrobacterium tumefaciens strain B6 were compared with respect to six characteristics, including 3-ketolactose production, lysogeny, octopine catabolism, tumorigenic host range, and plasmid content. Within this group of strains diversity was found for all characteristics except 3-ketolactose production. Six substrains were lysogenized with an omega-type phage, whereas one substrain appeared neither sensitive to nor lysogenized with this bacteriophage. All but two substrains catabolized octopine and induced tumors on carrot disks. These 18 substrains harbor deoxyribonucleic acid sequences homologous to pTiB6-806. The two substrains unable to catabolize octopine were nontumorigenic and lacked detectable Ti plasmid sequences. Of the 20 substrains, 13 also contained sequences homologous to the cryptic plasmid pAtB6-806; 2 of the 18 substrains tumorigenic on carrots failed to induce tumors on Kalanchoe leaves. Their inability to induced tumors on this host, could not be correlated with lysogeny, with the presence or absence of pAtB6-806, or with the very large cryptic plasmid recently described. The Ti plasmids from these two strains were indistinguishable from pTiB6-806 by restriction enzyme analysis and could genetically convert a cured A. tumefaciens strain to tumorigenicity on both plant species. The results with these two strains suggest that parameters of tumorigenicity, such as host range, may be controlled by the bacterial chromosome.
