Sinorhizobium fredii strain HN01 can use proline as the sole carbon and nitrogen source. A mutant strain GXHN100 unable to catabolize proline was screened from 6000 Tn5gusA5 random insertional mutants of S.fredii stra...
Sinorhizobium fredii RT19, a strain of free- living bacteria, was subjected to salt shock and its protein expression profiles were analyzed by differential display proteome approaches. The results of separation by two...

Previous investigations have shown that nifA gene is involved in nodulation and symbiotic nitrogen fixation regulation of Rhizobium. We study the role of nifA on nodulation of leguminous plants. We found that Sinorhiz...
