Project description:Identification of the specific WalR (YycF) binding regions on the B. subtilis chromosome during exponential and phosphate starvation growth phases. The data serves to extend the WalRK regulon in Bacillus subtilis and its role in cell wall metabolism, as well as implying a role in several other cellular processes.

Project description:Identification of the specific WalR (YycF) binding regions on the B. subtilis chromosome during exponential and phosphate starvation growth phases. The data serves to extend the WalRK regulon in Bacillus subtilis and its role in cell wall metabolism, as well as implying a role in several other cellular processes. For each sample analyzed in this study three biological replicates were performed. Three different samples were taken from a strain expressing the WalR-SPA protein as well as from wild-type (168) without a tagged WalR. Samples were taken from exponentially growing cells in low phosphate medium (LPDM) as well as from phosphate-limited cells (T2). Each sample compares ChIP DNA vs. Total DNA from the same cells.

Project description:RNA processing and degradation is initiated by endonucleolytic cleavage of the target RNAs. In many bacteria, this activity is performed by RNase E which is not present in Bacillus subtilis and other Gram-positive bacteria. Recently, the essential endoribonuclease RNase Y has been discovered in B. subtilis. This RNase is involved in the degradation of bulk mRNA suggesting a major role in mRNA metabolism. However, only a few targets of RNase Y have been identified so far. In order to assess the global impact of RNase Y, we compared the transcriptomes of strains expressing RNase Y or depleted for RNase Y. Our results indicate that processing by RNase Y results in accumulation of about 80 mRNAs. Some of these targets were substantially stabilized by RNase Y depletion, resulting in half-lives in the range of an hour. Moreover, about 40 mRNAs were less abundant when RNase Y was depleted among them the mRNAs of the operons required for biofilm formation. Interestingly, overexpression of RNase Y was sufficient to induce biofilm formation. The results emphasize the importance of RNase Y for B. subtilis and are in support of the idea that RNase Y is the functional equivalent of RNase E.

The results emphasize the importance of RNase Y for B. subtilis and are in support of the idea that RNase Y is the functional equivalent of RNase E. To study the global function of RNase Y, a microarray analysis was performed with a B. subtilis strain allowing controlled depletion of RNase Y. Strain GP193 (Commichau et al., 2009, Mol. Cell. Proteomics 8: 1350-1360) expressing the rny gene under the control of a xylose-inducible promoter was cultivated in CSE minimal medium in the presence or absence of the inducer xylose. The transcriptomes of the two cultures (i.e. expressing RNase Y and depleted for RNase Y) were compared at a timepoint at which the reduced RNase Y amounts already affected the mRNA turnover whereas the growth rates of the two cultures were still almost identical.
