Project description:The effect of overexpression HpHAP4-A, HpHAP4-B and ScYAP1 in Sc delta yap1 genetic background in native (no stress) and H2O2 oxidative stress conditions.
Project description:Clostridium acetobutylicum is a Gram-positive, endospore-forming bacterium that is considered as a strict anaerobe. It ferments sugars to the organic acids acetate and butyrate or shifts to formation of the solvents - ethanol, butanol and acetone. In most bacteria the major regulator of iron homeostasis is Fur (ferric uptake regulator). Analysis of the genome of Clostridium acetobutylicum has revealed three genes encoding Fur-like proteins. The amino acid sequece of one of them showed 70% similarity to the Fur protein of the closely related Bacillus subtilis.<br>Thus, to gain insight into the role of Fur and the mechanisms for maintenance of iron homeostasis in this strict anaerobic organism, we determined its transcriptional profile in response to iron limitation and inactivation of fur.
Project description:The met31 single delete and the met32 single delete strains were analyzed for genome-wide transcription at different times following Met4 hyeractivation and compared to cells that contain both Met31 and Met32.
Project description:We performed a gene expression analysis of C. albicans SC5314 planktonic cells exposed to the antifungal peptide ApoEdpL-W. Exponentially-growing C. albicans SC5314 cells in SD at 30°C medium were exposed to 2.5 µM ApoEdpL-W and samples were collected after 10 and 30 min. for transcript profiling
Project description:Most sRNAs control the expression of target genes by interacting with their mRNA. The fvr1 (Francisella virulence RNA 1) gene is found in the IGR between FTL_0777 and FTL_0778 and its sequence does not overlap those of the flanking genes, indicating that its target(s) is located in trans. Base-pairing between a sRNA and target mRNA generally leads to changed translation and often the stability of the mRNA is affected as well. Therefore, to identify possible targets of Fvr1, we compared the transcriptomes of the LVS?fvr1(LVS, for Live Vaccine Strain) and LVS/pfvr1+ strains after growth in liquid broth.
Project description:The objective of this study is to identify genes involved in arsenic stress and more particularly to see whether the presence of arsenic can highlight a link between mobility and oxidation
Project description:The study was conducted by comparing deleted and over-expression strains for SFL2 (CEC2001 and CEC1997, respectively) during a kinetic (0h, 2h and 4h) in YNB plus 2% casaminoacids (pPCK1- overexpression inducing conditions).
