Our previous work showed that an enoyl-ACP reductase gene fabI1 of Sinorhizobium meliloti was down-regulated in the nifA mutant nodule bacteria. To gain a better understanding of fabI1 gene, a single site insertion mu...
Some members of the heat shock protein 70 (HSP70) family have important functions in organism development. Here, we identified an alfalfa (Medicago sativa L. cv. Algonquin) HSP70 gene, MsHSP70-1, using cDNA array ...

Sinorhizobium meliloti nifA gene is required for the expression of a bunch of nif and fix genes. Here, we report its pleiotropic effects on the nodule formation. Compared with wild type strain, nifA mutant sig- nifica...
