Transcriptome of dehydrated vs hydrated Salmonella cells

ABSTRACT: Transcriptional profiles of dehydrated Salmonella Typhimurium SL1344 cells post 22h air drying were compared to those of SL1344 cells incubated for 22 h in DDW Two-condition experiment, dehydrated versus hydrated (control) Salmonella cells. Biological replicates: 4 control, 4 dehydrated, independently grown and harvested. One replicate per array.

ORGANISM(S): Salmonella enterica subsp. enterica serovar Typhimurium str. SL1344

Despite the scientific and industrial importance of desiccation tolerance in Salmonella, knowledge regarding its genetic basis is still scarce. In the present study, we performed a transcriptomic analysis of dehydrated and water-suspended Salmonella enterica serovar Typhimurium using microarrays. Dehydration induced expression of 90 genes and downregulated that of 7 genes. Ribosomal structural genes represented the most abundant functional group with a relatively higher transcription during dehy  ...[more]
