摘要 日本慢生根瘤菌 USDA122 III 型蛋白分泌系统（T3SS）的 rhcJ 和 ttsI 突变体未能分泌典型的效应蛋白，并获得了使 Rj2 大豆植物（Hardee）结瘤的能力，这与野生型 USDA122 共生不相容。这表明通过 T3SS 分泌的效应器触发了这两个伴侣之间的不相容性。
ABSTRACT The rhcJ and ttsI mutants of Bradyrhizobium japonicum USDA122 for the type III protein secretion system (T3SS) failed to secrete typical effector proteins and gained the ability to nodulate Rj2 soybean plants (Hardee), which are symbiotically incompatible with wild-type USDA122. This suggests that effectors secreted via the T3SS trigger incompatibility between these two partners.
