B. subtilis was grown in SMM media with glucose as carbon source and the samples for RNA were harvested OD578nm- 1.0). The stress conditions that were applied over here are growthat 57°C, 16°C, 1.2M Nacl and 37°C(control).
All the samples were analysed for transcriptome as biological triplicates.

I am PhD student at Prof.Uwe Voelker lab in Department of Functional Genomics. My area of research is microbial functional genomics in particular analysing the whole transcriptome(by microarray and other molecular biolology methods) of B.subtilis under various stress conditions.
I use QconCAT strategy for absolute quantification of carbon metabolic enzymes via MRM(multiple reaction monitoring) by LC-MS/MS.
I also perofrm experiments for understanding of dynamics of SigmaB network for modelling.
Modelling carbon core metabolism in Bacillus subtilis – Exploring the contribution of protein complexes in core carbon and nitrogen metabolism.
Bacillus subtilis is a prime model organism for systems biology approaches because it is one of the most advanced models for functional genomics. Furthermore, comprehensive information on cell and molecular biology, physiology and genetics is available and the European Bacillus community (BACELL) has a well-established reputation for applying
Bacillus subtilis was subjected to various stress conditions like high temperature(57°C), low temperature(16°C), high osmalarity(1.2M NaCl). The above mentioned stress conditions are again split into two different types as 'continuous stress condition' and 'sudden shock'. All the conditions were then done in biological triplicates.
Transcriptome for these samples was then analysed with Nimblegen Tiling array.

Recent studies revealed the unsuspected complexity of the bacterial transcriptome but its systematic analysis across many diverse conditions remains a challenge. Here we report the condition-dependent transcriptome of the prototype strain B. subtilis 168 across 104 conditions reflecting the bacterium's life-styles. This data set composed of 269 tiling array hybridizations allowed to observe ~85% of the annotated CDSs expressed in the higher 30% in at least one hybridization and thus provide an

B. subtilis was grown in M9 media with glucose as carbon source and the samples for RNA were harvested at OD600nm- 0.4 , 1.3 and 1.0 ). Culture was done at 37°C and samples at OD600nm- 0.4(Exponential), OD600nm- 1.3 (Early stationary), OD600nm-1.0(Late Stationary). All the samples were analysed for transcriptome as biological triplicates.
