| The entry into stationary phase causes a change in the pattern of gene expression of bacteria, when the cells must express a whole set of genes involved mainly with resistance to starvation and to environmental stresses. As an attempt to identify genes important for the survival of Caulobacter crescentus in stationary phase, we have screened a library of 5,000 clones generated by random transposon mutagenesis for mutants that showed reduced viability after prolonged growth. Four clones were selected, which displayed either lower viability or a longer time of recovery from stationary phase. The genes disrupted were identified, and the gene products were found to be mainly involved with amino acid metabolism (glutamate N-acetyltransferase,... |
