Project description:Initial attachment to a surface marks the onset of a bacterial life style switch from planktonic to biofilm mode of growth. Among dissimilatory iron reducing bacteria, S. oneidensis MR-1 is notable due to its extensive respiratory versatility. It has been hypothesized that direct interaction of Shewanella cells with, or close proximity to, an appropriate surface facilitates the deposition of electrons. In fact, Shewanella species have been demonstrated to adhere to various surfaces and form biofilms. Global transcriptome profiling was performed on cells in the transition to surface-associated growth using different surfaces and conditions to understand molecular mechanisms underlying the initiation of microbe-surface interactions and the switch from planktonic to sessile life style. In the study presented, expression profiles of two independent replicates of Shewanella oneidensis MR-1 wild type cells attached to glass for 0.25 h and 1 h, respectively, under hydrodynamic conditions were compared to two independent replicates of planktonic grown Shewanella oneidensis MR-1 wild type cells. Furthermore, expression profiles of two independent replicates of Shewanella oneidensis MR-1 wild type cells attached for 1 h to iron surface under hydrodynamic conditions were compared to two independent replicates of Shewanella oneidensis MR-1 wild type cells attached to glass for 1 h. All samples were obtained from aerobically grown cells in LM.

Project description:Purpose : Identification of the regulons directly and indirectly affected by the main regulators of flagellation in Shewanella putrefaciens CN-32 Methods : mRNA profiles were generated for Shewanella putrefaciens CN-32 samples by deep sequencing. The removal of ribosomal RNA was performed using the Ribo-Zero Bacteria Kit (Illumina) and cDNA libraries were generated with the ScriptSeq v2 Kit (Illumina) . The samples were sequenced in single end mode on an Illumina HiSeq 2500 device and mRNA reads were trimmed using the tool ‘cutadapt’ (version 3.5) with default settings and mapped to the NC_009438.1 (Shewanella putrefaciens CN-32) reference genome from NCBI using ‘bowtie2’ (version 2.3.5.1) with default settings for single-end sequencing.

Project description:The availability of oxygen is a major environmental factor for many microbes, in particular for bacteria, such as Shewanella species, which thrive in redox-stratified environments. One of the best studied systems involved in mediating the response to changes in environmental oxygen levels is the Arc two-component system of Escherichia coli, consisting of the sensor kinase ArcB and the cognate response regulator ArcA. An ArcA ortholog was previously identified in Shewanella, and as in E. coli, Shewanella ArcA is involved in regulating the response to shifts in oxygen levels. Here, we identified the hybrid sensor kinase SO_0577, now designated ArcS, as the previously elusive cognate sensor kinase of the Arc system in S. oneidensis MR-1. Phenotypic mutant characterization, transcriptomic analysis, protein-protein interaction and phosphotransfer studies revealed that the Shewanella Arc system consists of the sensor kinase ArcS, the single phosphotransfer domain protein HptA, and the response regulator ArcA. Phylogenetic analysis suggests that HptA might be a relict of ArcB. Conversely, ArcS is substantially different with respect to overall sequence homologies and domain organization. Thus, we speculate ArcS might have adopted the role of ArcB after loss of the original sensor kinase, perhaps as a consequence of regulatory adaptation to a redox-stratified environment. In the study presented, expression profiles of three independent replicates of Shewanella oneidensis MR-1 delta-arcS were compared to three independent replicates of Shewanella oneidensis MR-1 wild type cells. All samples were obtained from exponentially aerobically grown cells in LB
