Mutations in rpoBC suppress the defects of a Sinorhizobium meliloti relA mutant.

Abstract excerpt

The nitrogen-fixing symbiosis between Sinorhizobium meliloti and Medicago sativa requires complex physiological adaptation by both partners. One method by which bacteria coordinately control physiological adaptation is the stringent response, which is triggered by the presence of the nucleotide guanosine tetraphosphate (ppGpp). ppGpp, produced by the RelA enzyme, is thought to bind to and alter the ability of RNA...
