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.
Project description:To determine Sigma 54 (SigL) reglons in Bacillus thuringiensis HD73 strain, A sigLmutant, HD(ΔsigL::kan), was constructed with insertion of kanamycin resistance gene cassete. We have employed whole genome microarray expression profiling as a discovery platform to identify the difference of gene expression between mutant and wild-type strains.
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:Transcriptional profiling of C. elegans young adult worms cultured on non-pathogenic Bacillus subtilis strain 67 versus age-matched worms cultured on the control lab food E. coli OP50. The goal was to identify genes regulated in response to differences in diet, which potentially confer immunity to later exposures to pathogenic Bacillus thuringiensis DB27.
