TranscriptomicsGene expression comparison of P. atrosepticum and it's derivative vasH mutant
Effect of mutagenesis of a sigma 54-dependent transcriptional regulator encoding gene vasH (ECA3425) to global gene expression in P. atrosepticum SCRI1043 in planta mimicking conditions. Three biological replicates of the wild-type strain SCRI1043 and the mutant strain M-NM-^TvasH were grown in hrp ...

TranscriptomicsThe cold-induced two-component system CBO0366/CBO0365 regulates metabolic pathways with novel roles in cold tolerance of Group I Clostridium botulinum ATCC 3502
The two-component system CBO0366/CBO0365 was recently demonstrated to have a role in cold tolerance of Group I Clostridium botulinum ATCC 3502. The mechanisms under its control, ultimately resulting in increased sensitivity to low temperature, are unknown. A transcriptomic analysis with DNA microarr...

TranscriptomicsClostridium botulinum whole genome expression profile after heat shock in continous culture
Clostridium botulinum ATCC 3502 was grown in continuous culture at 39°C, subjected to heat shock at 45°C, and then continuously grown at 45°C. The goal was to determine the impact of stressful temperature to the whole genome expression profile and identify stress adaptation mechanisms. Time serie...

TranscriptomicsGene expression of Streptomyces turgidiscabies pathogenicity island
Gene expression in Streptomyces turgidiscabies pathogenicity island was studied after transferring cells into thaxtomin A inducing medium OBB using Agilent 60mer oligonucleotide array with probes designed for S.scabies and S.turgidiscabies. Gene expression study was used to confirm results of gene p...

TranscriptomicsComparison of genetic differences between Streptomyces scabies and turgidiscabies strains
Bacteria isolated from potato scab lesions in Finland or northern Sweden were analyzed using microarrays, PCR, and sequencing. Data indicate wide genetic variability in pathogenicity islands among S.turgidiscabies and S.scabies strains. Thirteen Streptomyces scabies and turgidiscabies strains from t...

TranscriptomicsMicroarray-based species identification of Streptomyces spp. isolated from potato scab lesions in Norway
28 Streptomyces strains isolated from common scab lesions of potato tubers from a wide geographic range in Norway, were selected for microarray analysis. The selected strains were subjected to species identification by microarray, 16S phylogenetic analysis and PCR; and microarray-based comparative g...

TranscriptomicsGene expression analysis of wild type Pectobacterium wasabie SCC3193 compared to a SCC3193 inactivation mutant of rsmA
Posttranscriptional regulator RsmA is part of a regulatory system that controls production of plant cell wall degrading enzymes (PCWDEs), motility and other virulence factors among the Pectobacterium spp of plant pathogens. We constructed the knockout mutation of rsmA gene in Pectobacterium wasabiae...

TranscriptomicsTranscriptomic analysis of (Group I) Clostridium botulinum ATCC 3502 cold shock response
Profound understanding of the mechanisms foodborne pathogenic bacteria utilize in adaptation to the environmental stress they encounter during food processing and storage is of paramount importance in design of control measures. Chill temperature is a central control measure applied in minimally pro...

TranscriptomicsComparative genomic hybridization analysis shows different epidemiology of chromosomal and plasmid-borne cpe-carrying Clostridium perfringens type A strains
Enterotoxin-producing C. perfringens type A is a common cause of food poisonings. The cpe encoding the enterotoxin can be chromosomal (genotype IS1470) or plasmid-borne (genotypes IS1470-like-cpe or IS1151-cpe). The chromosomal cpe-carrying C. perfringens are a more common cause of food poisonings t...
