摘要：

Of nine Bradyrhizobium japonicum serogroup 123 strains examined, 44% were found to be restricted for nodulation by cultivar Hill. Nodulation studies with soybean isoline BARC-2 confirmed that the soybean Rj4 allele restricts nodulation by the same serogroup 123 isolates. Immunological analyses indicated that B. japonicum strains in serogroups 123 and 31 share at least one surface somatic antigen.
