| Abstract: | A Rhizobium strain isolated from stem nodules of the legume Sesbania rostrata was shown to grow on atmospheric nitrogen (N(2)) as the sole nitrogen source. Non-N(2)-fixing mutants isolated directly on agar plates formed nodules that did not fix N(2) when inoculated into the host plant. |
