title: Isolation of a carbon starvation regulatory mutant in a marine Vibrio strain.
abstract: A carbon starvation-responding lac fusion of the marine Vibrio sp. strain S14 was used as a reporter strain in order to identify genes critical in the regulation of the carbon starvation response. Interestingly, sequence data together with an altered phenotype with respect to the accumulation of guanosine 3',5'-bispyrophosphate (ppGpp) imply that one of the genes (csrS) identified by this approach is an Escherichia coli spoT equivalent. Complementary data suggest that the function encoded by the csrS gene is essential for the successful development of starvation and stress resistance.
