(Submitter supplied) Vegetative cells of B. subtilis can recover from injury caused by high hydrostatic pressure (HHP) treatment at 250 MPa. DNA microarray analysis revealed that many ribosomal genes and translation relating factors (e.g. translation initiation factors) were induced during a growth-arrested phase after the HHP treatment. Expression of cold shock-responsive genes, whose products play key roles for efficient translation, and heat shock-responsive genes, whose product mediates the correct protein folding or degrades misfolded proteins, were also induced. more...

(Submitter supplied) The polyamine spermidine is not required for normal planktonic growth of Bacillus subtilis but is essential for robust biofilm formation. In a spermidine-deficient mutant of B. subtilis, the structural analogue norspermidine but not homospermidine restored biofilm formation. Intracellular biosynthesis of another spermidine analogue aminopropylcadaverine from exogenously supplied homoagmatine also restored biofilm formation. more...

(Submitter supplied) 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.

(Submitter supplied) Human Peptidoglycan Recognition Proteins (PGRPs) kill bacteria, likely by over-activating stress responses in bacteria. To gain insight into the mechanism of PGRP killing of Bacillus subtilis and bacterial defense against PGRP killing, gene expression in B. subtilis treated with a control protein (bovine serum albumin, BSA), human recombinant PGRP (PGLYRP4), gentamicin (aminoglycoside antibiotic), and CCCP (membrane potential decoupler) were compared. more...

(Submitter supplied) Bacillus subtilis strain AG174 was grown in the presence and absence of benzoate (30 mM). Benzoate was used in order to equalize the external and internal pH. The cultures were grown at external pH 7.0, and the addition of benzoate did not change the external pH. Microarray analysis was performed on cDNA synthesized from bacterial RNA. Real-time PCR of highly up-regulated genes confirmed the results of the microarray. more...

(Submitter supplied) Gene expression profiles of Bacillus subtilis strain AG174 were compared as a function of steady-state external pH during growth with aeration. Aerated overnight cultures were diluted 1:500 and incubated in 250 mL baffled flasks containing potassium-modified Luria-Bertani medium (LBK) buffered with 50 mM HOMOPIPES at pH 6.0, pH 7.0, and pH 9.0. Tubes were incubated at 37°C with aeration (260 rpm) to an optical density at 600 nm of 0.2. more...
