✦ Synopsis

The transformation of streptomycin resistance in Rhizobium ]aponicure was studied. The susceptible strain 211 was selected from sixty strains and one step mutant resistant to streptomycin in concentration I mg per 1 ml was used as the donor. The peak of the competence curve appeared at the ninth hour of growth; the frequency, when the homologous strain had been used was 0.01 p.c. The transformed resistance was of the same level as in the donor strain.
