[Cloning and identification of an Agrobacterium radiobacter 5D-1 chromosome fragment involved in control of nitrogen metabolism, biosynthesis of indolylacetic acid and replication of ColE1 plasmids].

Abstract excerpt

Pleiotropic chromosomal mutations were earlier identified in saprophytic associative bacterium Agrobacterium radiobacter 5D-1. The mutations changed nitrogen metabolism, disturbed synthesis of indolylacetic acid (IAA), and conferred the ability to sustain replication of ColE1 plasmid derivatives, which are not normally maintained in bacteria other than Escherichia. The mutations were designated Nr (Nitrogen...
