Comparative Transcriptomic Analysis of Salmonella in Desiccation

(Submitter supplied) To explore the mechanisms of Salmonella desiccation resistance, we studied the transcriptomic responses in Salmonella Tennessee (Tennessee), using S. Typhimurium LT2 (LT2), a strain weakly resistant to desiccation, as a reference strain. In response to 2 h air-drying at 11% equilibrated relative humidity, approximately one-fourth of the ORFs in the Tennessee genome and one-fifth in LT2 were differentially expressed (> 2-fold). more...

Transcriptomic profiling of Salmonella Typhimurium upon desiccation on stainless steel and subsequent rehydration

(Submitter supplied) Transcriptional profiles of Salmonella Typhimurium str. ST4/74 air-dried onto stainless steel for 4 h was compared to an early stationary phase (ESP) culture control. Cells that had been air-dried for 4 h were then subsequently rehydrated with water for a 30 min period, after which the transcriptional profile was compared to an ESP control.

Transcriptional and Physiological Responses of Bradyrhizobium japonicum to Desiccation-Induced Stress

(Submitter supplied) The growth and persistence of rhizobia and bradyrhizobia in soils are negatively impacted by drought conditions. In this study, we used genome-wide transcriptional analyses to obtain a comprehensive understanding of the response of Bradyrhizobium japonicum to drought. Desiccation of cells resulted in the differential expression of 15 to 20% of the 8,480 B. japonicum open reading frames, with considerable differentiation between early (after 4 h) and late (after 24 and 72 h) expressed genes. more...

General response of Salmonella enterica serovar Typhimurium to desiccation: A new role for the virulence factors sopD and sseD in survival.

(Submitter supplied) Salmonella can survive for long periods under extreme desiccation conditions. This stress response poses a risk for food safety, but relatively little is known about the molecular and cellular regulation of this adaptation mechanism. To determine the genetic components involved in Salmonella’s cellular response to desiccation, we performed a global transcriptomic analysis comparing Salmonella Typhimurium cells equilibrated to low water activity (aw 0.11) and cells equilibrated to high water activity (aw 1.0). more...

Desiccation and control transcriptomes of Rhodococcus jostii RHA1

(Submitter supplied) Here we report the first transcriptomic analysis of a Gram-positive bacterium to desiccation. Filtered RHA1 cells incubated at either low relative humidity (20%), as an air drying treatment, or high relative humidity (100%), as a control, were transcriptionally profiled over a comprehensive time series.

Sugar sweet springtails: On the transcriptional response of Folsomia candida (Collembola) towards desiccation stress

(Submitter supplied) Folsomia candida (Collembola) is able to survive dryer conditions by absorbing water vapour from its surroundings. To unravel the genomic responses underlying this intriguing water-absorption mechanism, we exposed the species to 98.2% Relative Humidity (eight, 27, 53 and 174 hours respectively) and subjected it to microarray based transcription profiling.

Expression data from non-infected and Salmonella Choleraesuis infected mesenteric lymph nodes

(Submitter supplied) To understand the host transcriptional response to S. enterica serovar Choleraesuis (S. Choleraesuis), the first generation Affymetrix porcine GeneChip® was used to identify differentially expressed genes in the mesenteric lymph nodes responding to infection at acute (8 hours (h), 24h, 48h post-inoculation (pi)) and chronic stages (21 days (d) pi) The objectives of this study were to identify and examine the stereotypical gene expression response within the host mesenteric lymph nodes to S. more...
