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:The gene expression of Bacillus subtilis 168 showed 3 major patterns including early expression, transition expression and late expression We monitored Bacillus subtilis gene expression by using microarray at differernt time points
Project description:In this study, we compared the transcriptome signatures in response to sodium hydrosulfide (NaHS), allicin and diallyl tetrasulfane (DAS4) exposure in the Gram-positive bacterium Bacillus subtilis. This analysis revealed that NaHS, allicin and DAS4 caused a similar thiol-specific oxidative and electrophile stress response as well as protein and DNA damage.
Project description:In the present study, we investigated the effect of Bacillus subtilis var. natto on lifespan using Caenorhabditis elegans as a model animal. The lifespan of the adult C. elegans fed Bacillus subtilis var. natto MI-OMU01 strain was significantly longer than that of animals fed OP50 (control). Transcriptional profiling comparing MI-OMU01- and control-fed animals suggested that genes related to “innate immune system” were upregulated by MI-OMU01.
Project description:This SuperSeries is composed of the following subset Series: GSE27650: Bacillus subtilis SigA ChIP-chip (BsubT1 array) GSE27665: Bacillus subtilis SigA ChIP-chip (BsubT2 array) Refer to individual Series
Project description:Plant growth-promoting rhizobacteria (PGPR) are soil beneficial microorganisms that colonize plant roots for nutritional purposes and accordingly benefit plants by increasing plant growth or reducing disease. But it still remains unclear which mechanisms or pathways are involved in the interactions between PGPR and plants. To understand the complex plant-PGPR interactions, the changes in the transcriptome of typical PGPR standard Bacillus subtilis in responding to rice seedlings were analyzed. We compared and anylyzed the transcriptome changes of the bacteria Bacillus subtilis OKB105 in response to rice seedings for 2 h. Total RNA was extracted and Random priming cDNA synthesis, cDNA fragmentation and terminal labeling with biotinylated GeneChip DNA labeling reagent, and hybridization to the Affymetrix GeneChip Bacillus subtilis Genome Array.
