Expression profile for higA mutant of Pseudomonas aeruginosa PA14

Project description:The previously uncharacterized proteins HigB (unannotated) and HigA (PA4674) of Pseudomonas aeruginosa PA14 were found to form a type II TA system in which antitoxin HigA masks the RNase activity of toxin HigB through direct binding. To determine the physiological role of HigB/HigA in P. aeruginosa, a whole-transcriptome experiment was performed for the higA antitoxin deletion mutant of the PA14 strain compared to the wild-type PA14 strain. The rationale was that for the strain that lacks the antitoxin, the effect of the toxin could be discerned due to enhanced activity of the toxin. Furthermore, toxin HigB reduces production of the virulence factors pyochelin, pyocyanin, swarming, and biofilm formation.

topA mutant of P. aeruginosa PA14

Project description:We have tested the effect of deletion of Topoisomerase I on genes transcription of the bacteria Pseudomonas. aeruginosa. Topoisomerase I is a conserved protein that modulate the topology state of the DNA from super-coiled to relaxed. To this end we have compared the transcription profile of a topA::GentR mutant to that of the wild-type strain. The topA mutant contains in topA gene a Mariner transposon with a gentamicin resistance cassette. It is part of the non-redundant mutant library of P. aeruginosa PA14 strains. WT and mutant cells were grown to OD 2.0 in LB 200rpm shaking at 37C.

Transcriptional modulation of Quoring-sensing signaling throught QslA in Pseudomonas aeruginosa PA14 and PAO1.

Project description:To further determine the origin of the increased virulence of Pseudomonas aeruginosa PA14 compared to Pseudomonas aeruginosa PAO1, we report a transcriptomic approach through RNA sequencing. Next-generation sequencing (NGS) has revolutioned sistems-based analsis of transcriptomic pathways. The goals of this study are to compare the transcriptomic profile of all 5263 orthologous genes of these nearly two strains of Pseudomonas aeruginosa.
