Phenotypic and transcriptomic analyses of Sigma L-dependent characteristics in Listeria monocytogenes EGD-e

► Phenotypic and gene expression roles of σL in Listeria monocytogenes were examined. ► σL promotes resistance to a wide range of environmental and chemical stresses. ► Genome wide transcriptome analysis confirmed σL control on various genes. ► σL-controlled genes uncovered are involved in execution of diverse cellular functions. ► σL is a global transcription regulator vital in L. monocytogenes stress adaptation.
