Transcriptome of continuously stressed B. subtilis

SysMO is a European transnational funding and research initiative on "Systems Biology of Microorganisms".

The goal pursued by SysMO was to record and describe the dynamic molecular processes going on in unicellular microorganisms in a comprehensive way and to present these processes in the form of computerized mathematical models.

Systems biology will raise biomedical and biotechnological research to a new quality level and contribute markedly to progress in understanding. Pooling European research ...

BaCell-SysMO 2 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.

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.

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.

Data for three biological replicates of control culture and 37°C and 57°C in the file.
