| Outline of Final Research Achievements |
We identified a novel gene (orf5208) in a soybean symbiont Bradyrhizobium elkanii which affected root nodule symbiosis with soybean. The orf5208 encoded a putative secreted protein and was shown to inhibit nodule formation on Rj4 soybean while it promoted nodule formation on non-Rj4 soybean. Furthermore, orf5208 was shown to be essential for the nodule formation on soybean mutant that had a defect in early symbiosis signaling. Taken together, orf5208 promotes nodule formation via the novel pathway that bypasses the early symbiosis signaling.
