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:To determine Sigma 54 (SigL) reglons in Bacillus thuringiensis HD73 strain, A sigLmutant, HD(M-NM-^TsigL::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. 2 ml samples were separately harvested from B. thuringiensis HD73 and HD(M-NM-^TsigL::kan) strains grown in SchaefferM-bM-^@M-^Ys sporulation medium (SSM) at stages T7 of stationary phase (7 hours after the end of the exponential phase). Three independent repeats were performed for each stain.
Project description:Bacillus thuringiensis is an important microbial insecticide for controlling agricultural pests. We report the finished genome sequence of Bacillus thuringiensis serovar israelensis strain HD-789, which contains genes encoding 7 parasporal crystals consisting of Cry4Aa3, Cry4Ba5 (2 genes), Cry10Aa3, Cry11Aa3, Cry60Ba3, and Cry60Aa3, plus 3 Cyt toxin genes and 1 hemagglutinin gene.
