Project description:Genomic microarrays were used to examine the complex temporal program of gene expression exhibited by bacteriophage T4 during the course of development.The microarray data confirm the existence of distinct early, middle, and late transcriptional classes during the bacteriophage replicative cycle.This approach allows assignment of previously uncharacterized genes to specific temporal classes.The genomic expression data verify many promoter assignments and predict the existence of previously unidentified promoters. Keywords: time course

Project description:Bacteriophages are highly abundant viruses of bacteria. The major role of phages in microbial ecology to shape bacterial communities and their emerging medical potential as antibacterial agents have triggered a rebirth of phage research. It is of particular interest to understand the molecular mechanisms by which phages gain control over their host. Omics technologies such as next-generation sequencing and protein-profiling technologies can provide novel insights into transcriptional and translational events occurring during the infection process. Thereby, the temporal organization of the transcriptome and proteome of the phage and their bacterial hosts can be monitored. In this study, we performed next-generation sequencing and proteomics to study the transcriptome and proteome of the T4 phage and its host during the infection in a time-resolved manner. Our data shows the temporally resolved appearance of bacteriophage T4 transcripts and proteins, confirming previously described subgrouping of T4 gene products into early, middle and late infection phases. We observe specific early transcripts giving rise to middle or late proteins indicating the existence of previously not reported post-transcriptional regulatory mechanisms controlling the translation of T4 mRNAs. Moreover, we investigated the stability of E. coli-originated transcripts and proteins in the course of infection, identifying degradation of E. coli transcripts and preservation of the host proteome. This study provides the first comprehensive insights into the transcriptomic and proteomic takeover by the bacteriophage T4, exemplifying the power and value of high-throughput technologies to simultaneously characterize multiple gene expression events. Moreover, we created a user-friendly application available to the entire scientific community to access gene expression patterns for their host and phage genes of interest.

Project description:Bacteriophages are highly abundant viruses of bacteria. The major role of phages in shaping bacterial communities and their emerging medical potential as antibacterial agents has trig-gered a rebirth of phage research. To understand the molecular mechanisms by which phages hijack their host, omics technologies can provide novel insights into the organization of tran-scriptional and translational events occurring during the infection process. In this study, we ap-ply transcriptomics and proteomics to characterize the temporal patterns of transcription and protein synthesis during T4 phage infection of E. coli. We investigated the stability of E. coli-originated transcripts and proteins in the course of infection, identifying degradation of E. coli transcripts and preservation of the host proteome. Moreover, the correlation of the phage transcriptome and proteome reveals specific T4 phage mRNAs and proteins that are temporally decoupled, suggesting post-transcriptional and translational regulation mechanisms. This study provides the first comprehensive insights into the molecular takeover of E. coli by bacteriophage T4. This data set represents a valuable resource for future studies seeking to study molecular and regulatory events during infection. We created a user-friendly online tool, POTATO4, available to the scientific community to access gene expression patterns for E. coli and T4 genes.

Project description:We investigated the effect of the T4 MotB protein on E. coli gene expression. E. coli BL21 (DE3) containing either pNW129 or pNW129-MotB were grown to early log phase (OD600 ~ 0.3) then induced with 0.2% arabinose for 20 minutes. T4 phage added to the culture at MOI10. Cells were then harvested at 5 min.
