Photosynthetic Bradyrhizobium sp. Strain 0RS285 Is Capable of Forming Nitrogen-Fixing Root Nodules on Soybeans (Glycine max).

The ability of photosynthetic Bradyrhizobium strains 0RS285 and 0RS278 to nodulate soybeans was investigated. While the nod gene-deficient 0RS278 strain induced bumps only on soybean roots, the nod gene-containing 0RS285 strain formed nitrogen-fixing nodules. However, symbiotic efficiencies differed drastically depending on both the soybean genotype used and the culture conditions tested. [ABSTRACT FROM AUTHOR]
