LYSOGENY IN RHIZOBIUM LEGUMINOSARUM AND R. TRIFOLII
Seven lysogenic bacteria strains, three of Rhizobium leguminosarum and four of R. trifolii, were identified among a total of 54 strains from these two species and R. phaseoli. The R. leguminosarum strains may be multiply lysogenic; two of them also produce lethal agents resembling bacteriocins in their effect. Lysogeny was confirmed by standard criteria of uv-inducibility, selfimmunity, and reductive ability. Lysogenic conversion involving symbiotic characteristics was not observed. A minimum of six different temperate phage and two clearplaque- forming variant phage were identified. The-host range includes strains of the above three rhizobial species, but not of R. melilotii. Variation in host specificity of some phage following host passage is under investigation. (auth)
