Project description:Plant drought stress response and resistance are complex biological processes that merit systems-level analyses to dissect drought stress encountered by crops in the field. We have used gene expression profiling of Arabidopsis plants subjected to a controlled, sublethal, moderate drought (mDr) treatment to characterize early and late response to drought. We have also compared these profiles to those from plants treated with soil water deficit (progressive) drought (pDr) to reveal acclimation responses in plants. Controlled moderate drought (mDr) was maintained by giving Arabidopsis (Columbia) plants water to keep the soil moisture level at 30% of field capacity, which is 200% or 2 g H2O g-1 dry soil. Water was withheld at 30 days after sowing (DAS). For progressive drought (pDr) treatment, plants were grown in a growth room as described above, water was withheld at 35 DAS, and were allowed to dry until the required pDr level was reached. For RNA isolation, two biological replicate samples of 5 pooled plants were collected at early (day1) and late stage (day10) for mDr, and first day of wilting for pDr, along with controls for mDr and pDr. Samples were hybridized to the Affymetrix (ATH1 25K) GeneChip.
Project description:The DNA microarray was employed in this study to investigate the gene expression profiles of Escherichia coli treated by an oil-in-water (o/w) microemulsion, in order to better understand the antimicrobial mechanism of the microemulsion as a promising food-grade antimicrobial system. 5,440 open reading frames (ORFs) of E. coli were investigated.
Project description:Primary objectives: The study investigates whether a Escherichia coli Nissle-suspenison has a (preventive) antidiarrheal effect in patients with tumors who are treated with chemotherapeutic schemes which are associated with increased occurances of diarrhea. Diarrhea caused by treatment are thought to be reduced in intensity and/or frequency by the treatment with Escherichia coli Nissle-Suspension.
Primary endpoints: Common toxicity criteria (CTC) for diarrhea
Project description:Escherichia coli K-12 BW25113 were cultured in the LB and M63 media. Exponetially growing populations were collected for RNAseq. The culture medium-induced transcriptional changes were analyzed.
Project description:This dataset contains RNA-seq profiles of Escherichia coli K-12 MG1655 collected under a variety of conditions to enable transcriptional regulatory network (TRN) analysis using the iModulon framework.
Project description:The purpose of this study is to determine whether the presence of pathogenic Escherichia coli in colon is associated with psychiatric disorders.
