Photosynthetic Bradyrhizobium sp. strain ORS285 is capable of forming nitrogen-fixing root nodules on soybeans (Glycine max)

Giraud E., Xu L., Chaintreuil C., Gargani D., Gully D., Sadowsky M.. 2013. Applied and Environmental Microbiology, 79 (7) : p. 2459-2462.

The ability of photosynthetic Bradyrhizobium strains ORS285 and ORS278 to nodulate soybeans was investigated. While the nod gene-deficient ORS278 strain induced bumps only on soybean roots, the nod gene-containing ORS285 strain formed nitrogenfixing nodules. However, symbiotic efficiencies differed drastically depending on both the soybean genotype used and the culture conditions tested. (Résumé d'auteur)
