RNA-seq of Escherichia coli K-12 MG1655 and Stx2 phage lysogens

Project description:Here, we investigated the impact of Stx2 phage carriage on Escherichia coli (E. coli) K-12 MG1655 host gene expression. Using quantitative RNA-seq analysis, we compared the transcriptome of naïve MG1655 and the lysogens carrying the Stx2 phage of the 2011 E. coli O104:H4 outbreak strain or of the E. coli O157:H7 strain PA8, which share high degree of sequence similarity.

Gene expression of Ustilago maydis SG200, SG200M-bM-^HM-^Fhxt1 and the avirulent SG200M-bM-^HM-^Fhxt1 hxt1(R164K) on maize leaf surface

Project description:Hxt1 is a high affinity hexose transporter important for virulence of the phytopathogenic basidiomycete Ustilago maydis on its host plant maize. Hxt1 shows the highest similarities to the glucose sensors Rgt2 and Snf3 from S. cereviciae (42% and 39% identity on amino acid level, respectively). In these sensors, the substitution of a highly conserved arginine to lysine leads to a constitutive active signal, resulting in expression of several glucose induced genes. Introduction of an analogous mutation in Hxt1 leads to loss of transport activity in the resulting Hxt1(R164K) protein. Expression of Hxt1(R164K) in hxt1 deletion strains results in a completely avirulent phenotype. Pathogenic developement of M-bM-^HM-^Fhxt1 hxt1(R164K) strains is blocked immediately after plant penetration. Expression analysis of M-bM-^HM-^Fhxt1 hxt1(R164K) cells 24 hours post inoculation revealed downregulation of a set of genes involved in carbohydrate metabolism indicating a role of Hxt1 in carbohydrate signaling during initiation of the pathogenic stage. To analyze expression changes of SG200 and SG200M-bM-^HM-^Fhxt1 and SG200M-bM-^HM-^Fhxt1 hxt1(R164K) cells were harvested from the surface of maize leaves 24 hour post inoculation. For each strain three independent replicates were conducted.

ChIP-chip data of Thp1-Flag and Sac3-Flag in wild-type cells, and Rrm3-Flag in sac3M-bM-^HM-^F and thp1M-bM-^HM-^F cells

Project description:Transcription is a major obstacle for replication fork progression and a cause of genome instability. Such instability increases in mutants with a suboptimal assembly of the nascent messenger ribonucleo-protein particle (mRNP), as THO/TREX and the NPC-associated THSC/TREX-2 complex. Here we show that yeast sac3M-bM-^HM-^F and thp1M-bM-^HM-^F cells accumulate genome-wide replication obstacles as determined by the distribution of the Rrm3 helicase. Such obstacles preferentially occur at long and highly expressed genes, to which Sac3 and its interacting partner Thp1 are preferentially bound in wild-type cells. ChIP-chip studies were perfomed with antibodies against Flag-tagged Thp1 and Sac3 proteins in wild-type cells of the yeast S. Cerevisiae, as well as Flag-tagged Rrm3 protein in sac3M-bM-^HM-^F and thp1M-bM-^HM-^F cells that were compared with Rrm3 in wild-type cells from Santos-Pereira et al., 2013 (accession number GSE50185).
