title: Cold shock induction of the cspL gene in Lactobacillus plantarum involves transcriptional regulation.
abstract: Fragments of the cspL promoter region were fused to the gusA reporter and reintroduced into Lactobacillus plantarum cells, either on multicopy plasmids or through single-copy chromosomal integration. beta-Glucuronidase activity and primer extension data demonstrate that the cspL promoter is induced in response to cold shock and that multicopy constructs quench the induction of the resident cspL gene.
