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.
在研究的 9 株大豆根瘤菌 123 血清型菌株中,有 44%被发现受到品种 Hill 的限制结瘤。与大豆品系 BARC-2 的结瘤研究证实,大豆 Rj4 等位基因限制了同一血清群 123 分离株的结瘤。免疫分析表明,血清群 123 和 31 的大豆根瘤菌菌株至少共享一种表面体抗原。
