Project description:Investigation of whole genome gene expression level changes in sporulating Bacillus subtilis 168 delta-prpE mutant, compared to the wild-type strain. The mutation engineered into this strain results in impaired germination of spores. A six chip study using total RNA extracted from three separate wild-type cultures of sporulating Bacillus subtilis 168 and three separate cultures of sporulating mutant strain, Bacillus subtilis 168 delta-prpE, in which prpE (yjbP BSU11630) gene coding for a protein phosphatase is deleted entirely. Each chip consists of four fields able to measure the expression level of 4,104 genes from Bacillus subtilis subsp. subtilis strain 168 NC_000964 with eight 60-mer probe pairs (PM/MM) per gene, with two-fold technical redundancy.
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:Soybeans fermented by Bacillus subtilis BJ3-2 exhibits strong ammonia taste in medium temperature below 37℃ and prominent soy sauce-like aroma moderate temperatures above 45℃. The transcriptome sequencing of Bacillus subtilis BJ3-2 (incubating at 37°C and 45°C) has been completed, screening of differentially expressed genes (DEGs) through data analysis, and analyzing their metabolic pathways, laying a foundation for exploring the regulatory mechanism of soy sauce-like aroma formation.
Project description:Investigation of the kinetics of whole genome gene expression level changes in Bacillus subtilis NDmed strain during formation of submerged biofilm and pellicle. The Bacillus subtilis NDmed strain analyzed in this study is able to form thick and highly structured submerged biofilms as described in Bridier et al., (2011) The Spatial Architecture of Bacillus subtilis Biofilms Deciphered Using a Surface-Associated Model and In Situ Imaging. PLoS ONE 6(1):e16177.
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
