TranscriptomicsTranscriptional profiles from Dickeya dadantii 3937 in various growth conditions
We have analysed the global gene expression of the plant pathogen Dickeya dadantii 3937 when grown in vitro under different growth and stress conditions. A multi-factorial design with 32 different experimental conditions was constructed, with two biological replicates for each condition. Cells were ...

no omics definedTranscription profiling of E. coli LZ41 and LZ54 strains containing drug-resistant alleles of different topoisomerase genes treated with norfloxacin
Effect of FIS and H-NS on gene expression at relexed and hypernagative supercoiling level using LZ41 and LZ54 strains. LZ41 and LZ54 strains contain drug-resistant alleles of different topoisomerase genes. LZ41 strain treatment norfloxacin strongly relaxes DNA, whereas in LZ54 strain the same trea...

no omics definedTranscription profiling of E. coli LZ41 and LZ54 strains containing drug-resistant alleles of different topoisomerase genes treated with norfloxacin
Effect of supercoiling level on gene expression using LZ41 and LZ54 strains containing drug-resistant alleles of different topoisomerase genes. LZ41 strain treatment with norfloxacin strongly relaxes DNA, whereas in LZ54 strain the same treatment generates high negative supercoiling (Khodursky et al...

TranscriptomicsGM - E. coli - LZ fishns Act Rep
Comparison of transcript profiles of E. coli LZ41fishns and LZ54fishns strains containing drug-resistant alleles of different topoisomerase genes to distinguish gene transcripts associated either with relaxation or hypernegative supercoiling.

TranscriptomicsGM - E. coli - SetB LZ fishns Hyp Rel
Comparison of transcript profiles of E. coli LZ41 and LZ54 fishns mutant strains containing drug-resistant alleles of different topoisomerase genes to distinguish gene transcripts associated either with relaxation or hypernegative supercoiling in absence of transcriptional regulator FIS and H-NS.

TranscriptomicsTranscription profiling of E. coli CSH50 wild type and hupA::cm hupB::kan double mutant cells
Comparison of transcript profiles of E. coli CSH50 wild-type and CSH50 hupA::cm hupB::kan double mutant cells to distinguish between the genes expressed either in the presence or absence of HU during log phase.

TranscriptomicsAnalysis of DNA relaxation in Dickeya dadantii wild type, fis and hns strains
We have analyzed the transcriptomes of Dickeya dadantii wild type, fis and hns strains in condition of DNA relaxation induced by novobiocin, a DNA gyrase inhibitor. For DNA relaxation novobiocin was added for 15 min to 100µg/ml final concentration to exponentially growing wild type, hns and fis stra...
