Project description:High-resolution mapping of the pCAR1 plasmid transcriptomes in the original host Pseudomonas resinovorans CA10 and the transconjugant Pseudomonas putida KT2440(pCAR1) While plasmids are replicated autonomously in their hosts, the transcription of plasmid genes can be switched through horizontal transfer by the change in the transcriptional networks. To examine whether and how the plasmid genome is differentially expressed, we analyzed the transcriptomes of the 199,035-bp IncP-7 carbazole catabolic and conjugative plasmid pCAR1 in the original host Pseudomonas resinovorans CA10 and the transconjugant Pseudomonas putida KT2440(pCAR1) during growth on carbazole or succinate using the high-resolution tiling array. The tiling array successfully detected the relatively large catabolic operons, for which transcription was induced during growth on carbazole regardless of the host. Compared between the hosts, nearly identical regions of pCAR1 were transcribed, but two hypothetical operons, i.e., ORF100-108 and ORF145-146, were transcribed at higher levels in KT2440(pCAR1) than in CA10. We verified the differential expression in heterologous hosts using quantitative RT-PCR. The tiling array analysis clearly revealed the transcription start sites, for which the positions and extents agreed with the primer extension experiments. Our data demonstrate that the transcriptome of the transmissible plasmid is altered through horizontal transfer, and we identified probable genes that are involved in plasmid functions in various hosts. This approach can be used to visualize flexible prokaryotic transcriptomes comprehensively. Keywords: high-resolution RNA mapping

Project description:The completely sequenced catabolic plasmid pCAR1 of Pseudomonas resinovorans CA10 confers the ability to degrade carbazole upon the recipient strain Pseudomonas putida KT2440. To study the coordinated expression of pCAR1 with its host chromosome, transcriptome of the transconjugant strain KT2440(pCAR1) was analyzed at growth with carbazole as the sole carbon source compared to succinate as an alternative carbon source. Next, horizontal gene transfer of a plasmid potentially alters the transcriptome of its host chromosome. Transcriptome of the transconjugant strain KT2440(pCAR1) was compared to the parental strain KT2440 at the same growth conditions. Furthermore, pCAR1 encodes a possible global regulator designated ORF70, which belongs to the MvaT family of H-NS-like nucleoid-associated proteins in Pseudomonas. To investigate the regulon under the control of ORF70, transcriptome of KT2440(pCAR1deltaORF70) was compared to the parental strain KT2440(pCAR1) at the same growth conditions.

Project description:MvaT proteins are recognized as a member of H-NS family proteins in pseudomonads. IncP-7 conjugative plasmid pCAR1, which was originally found in Pseudomonas resinovorans, carries an mvaT homologous gene, pmr. In Pseudomonas putida KT2440 bearing pCAR1, it was previously reported that pmr and chromosomally-encoded homologous genes, turA and turB, are majorly transcribed, and that Pmr interacts with TurA and TurB in vitro (Yun et al. J. Bacteriol. 192:4720-4731, 2010). In the present study, we clarified how the three MvaT proteins regulate the transcriptome of P. putida KT2440(pCAR1). Modified ChIP-chip analyses suggested that the binding sites of Pmr, TurA, and TurB in P. putida KT2440(pCAR1) genome were almost identical; nevertheless, transcriptome analyses using deletion mutants of each MvaT protein gene at the log and early-stationary growth phases clearly suggested that their regulons were different with one another. Especially, significant dissimilarity of regulons was found between Pmr and other two proteins. Transcriptions of the larger number of genes were affected by Pmr deletion at the early-stationary phase than at the log phase, suggesting that Pmr minimizes the pCAR1 effects on host fitness more effectively at the early-stationary phase. On the other hand, similarity found between the regulons of TurA and TurB implied that they may have complementary roles as global transcriptional regulators in response to the plasmid carriage. ChIP-chip: Pseudomonas putida KT2440 harboring plasmid pCAR1 cells were ChIPed with His-tag (C-terminus of each MvaT homologs) and compared with input control. Transcriptome analysis: pCAR1 RNA maps of mvaT deletion mutants were compared with those of wild-type cells.
