Abstract excerpt
Rhizobium meliloti mutants carrying ndvF insertion or deletion mutations induce nodules on alfalfa which contain very few infected cells and fail to fix N2 (Fix-). We have characterized five independent second site mutations (designated sfx) which completely suppress the Fix- phenotype of ndvF mu...
