Project description:These transcriptomic data are used in two distinct but subsequent and complementary studies:(i) the role of the mfsR gene on the expression of the mfsABC operon as well as on its own promoter, (ii) the role of the mfsR operon on the activation of the core genes of ICEclc. ICEclc-specific gene expression in Pseudomonas putida UWC1 was measured during exponential phase and the subsequent stationary phase (sole carbon and energy sources : 10mM 3-chlorobenzoate). 6 genotypes were tested: (i) wild type P. putida UWC1 ICEclc (strain nM-BM-02737) ; (ii) P. putida UWC1 ICEclc-KmR19033 (strain nM-BM-02961) ; (iii) P. putida UWC1 ICEclcM-bM-^HM-^F'mfsR (strain nM-BM-04322) ; (iv) P. putida UWC1 ICEclcM-bM-^HM-^F'orf17984 (strain nM-BM-04372) ; (v) P. putida UWC1 ICEclcM-bM-^HM-^F'tciR (strain nM-BM-04321) ; (vi) P. putida UWC1 ICEclcM-bM-^HM-^FmfsR-M-bM-^HM-^F'orf17984 (strain nM-BM-03543). For each strain, in each phase, 3 or 4 replicates were used.
Project description:We analyzed gene expression during conjugative transfer of plasmid RP4. Pairs of rifampicin-susceptible (RifS) and -resistance (RifR) strains of Pseudomonas putida KT2440 were conjugated for 10 minute on filter membrane in the presence of rifampicin to discriminate the expression changes in the donor and recipient cells.
Project description:The impact of the conjugative plasmid pCAR1, which is involved in carbazole degradation, on the succinylome of host Pseudomonas putida KT2440 was investigated using a stable isotope labeling by amino acids in cell culture (SILAC)-based quantitative analysis. This dataset is related to PXD007089.
Project description:KaiC is the central cog of the circadian clock in Cyanobacteria. Close homologs of this protein are widespread among bacteria not known to have a circadian physiology. The function, interaction network, and mechanism of action of these KaiC homologs are still largely unknown. Here, we focus on KaiC homologs found in environmental Pseudomonas species. We characterize experimentally the only KaiC homolog present in Pseudomonas putida KT2440 and Pseudomonas protegens CHA0. Through phenotypic assays and transcriptomics, we show that KaiC is involved in osmotic and oxidative stress resistance in P. putida and in biofilm production in both P. putida and P. protegens.

Project description:The impact of the conjugative plasmid pCAR1, which is involved in carbazole degradation, on the proteome, acetylome, and succinylome of host Pseudomonas putida KT2440 was investigated using a stable isotope labeling by amino acids in cell culture (SILAC)-based quantitative analysis.
