title: Behavioral mutants of Rhizobium meliloti.
abstract: Rhizobium meliloti exhibited behavior resembling that of other chemotactic bacteria. Nonflagellated, nonmotile but flagellated, and nonchemotactic mutants were isolated, and genetic mapping placed all three types of lesions within a small region of the R. Meliloti chromosome. Results from nodulation experiments performed with these mutants indicate that members of the three classes (Fla-, Mot-, and Che-) infect and produce as many nodules on alfalfa plants as does the wild-type strain.
