abstract：:Quorum sensing of Sinorhizobium meliloti relies on N-acyl-homoserine lactones (AHLs) as autoinducers. AHL production increases at high population density, and this depends on the AHL synthase SinI and two transcriptional regulators, SinR and ExpR. Our study demonstrates that ectopic expression of the gene rne, coding ...

The mutation was shown to be in rplX, the gene for protein L24, and was due to the alteration of an AAA codon to a TAA stop codon at position 61 in rplX that resulted in a 20-amin...
