Abstract excerpt

In Rhizobium meliloti, expression of the nodulation genes (nod and nol genes) is under both positive and negative controls. These genes are activated by the products of the three related nodD genes, in conjunction with signal molecules from the host plants. We showed that negative regulation is mediated by a repressor protein, binding to the overlapping nodD1 and nodA as well as to the nodD2 promoters. The...
