Primary succession is predicted to proceed through shifts from stress-tolerant to competitive to cooperative ecological strategies as resource availability increases, yet molecular evidence for these transitions in microbial systems remains limited. Here, we used an integrated m...
High-affinity iron (Fe) scavenging compounds, or siderophores, are widely employed by soil bacteria to survive scarcity in bioavailable Fe. Siderophore biosynthesis relies on cellular carbon metabolism, despite reported decrease in both carbon uptake and Fe-containing metabolic proteins in Fe-def...
Barophilic growth of the hyperthermophilic methanarchaeon Methanocaldococcus jannaschii occurred when gas-substrate availability did not limit growth. In contrast, when growth was limited by gas transfer, no enhancement of growth was evident and a stress response was exhibited at both high and low p...
Transcription profiling of P. gingivalis W50 grown in continuous culture under conditions of heme-excess and heme-limitation. Reference design (using Cy5 labelled genomic DNA as the reference) to compare two conditions: heme-excess vs heme-limitation. Three samples for each condition, independently...
A time series of whole-genome transcription profiling of E. coli K-12 W3110 was performed to study the dynamic physiological response of E. coli K-12 W3110 to limited carbon conditions. cDNA from eight time intervals after glucose limitation, representing different stages of glucose depletion, along...
The experiment was intended to reveal the transcriptional changes of H. salinarum cells in response to phosphate limitation. Because nothing was known neither about the nature of transcriptional changes nor about the kinetic of it, we analysed the transcriptome dynamics over a time range of 24 hours...
