Project description:Test whether it is possible to conjugate a whole plasmid library into a recipient strain without loss of fidelity (as judged by aCGH analysis)
Project description:Test whether it is possible to conjugate a whole plasmid library into a recipient strain without loss of fidelity (as judged by aCGH analysis) Donor and Recipient Libraries are compared with array CGH to detect copy number differences, a simple selection experiment is also performed
Project description:In this study, we analyzed the expression profiles of a virulence plasmid-cured strain and wild-type strain of shigella flexneri. The results showed that the genes of glp regulon were upregulated in mutant bacteria in stationary phase cultures.
Project description:To further explore potential molecular mechanisms and pathways by which the presence or absence of the pGKT2 plasmid may be affecting the overall fitness cost in the native Gordonia sp KTR9 strain, transcriptome studies were performed. Transcriptome experiments comparing KTR9 wild-type and mutant strains grown in rich media confirmed the loss of the pGKT2 plasmid and also indicated the loss of the 90 kb pGKT1 plasmid.
Project description:To further explore potential molecular mechanisms and pathways by which the presence or absence of the pGKT2 plasmid may be affecting the overall fitness cost in a transconjugant Rhodococcus jostii RHA1 strain, transcriptome studies were performed. Transcriptome experiments comparing RHA1 wild-type and RHA1 transconjugant strains grown in rich media confirmed the presence of the pGKT2 plasmid.
Project description:We have developed two methods for efficiently consructing RNA-seq libraries using transposition. Each method constructs high quality RNA-seq libraries when compared to standard approaches. One of the methods (Directional Tn-RNA-seq) maintains strand-of-origin information and exhibits strand specificity comparable to current approaches.

Each method constructs high quality RNA-seq libraries when compared to standard approaches. One of the methods (Directional Tn-RNA-seq) maintains strand-of-origin information and exhibits strand specificity comparable to current approaches. RNA-seq libraries were constructed from ECC-1, a human cell line, and Universal Human Reference RNA using transposon-based and standard RNA-seq library construciton methods.
