Expression of symbiotic genes of Rhizobium japonicum USDA 191 in other rhizobia.

abstract：:Among 69 ColE3 mutant plasmids selected on the basis of their inability to produce an active colicin, seven (cop-1 to cop-7) were found to bear a mutation affecting the structural gene for colicin. Three of these (cop-1, cop-2 and cop-3) lead to the production of an inactive colicin molecule which has the same molecul...
