Mycoplasma gallisepticum S6 - Transcriptome analysis reveals novel regulatory mechanisms in a genome-reduced bacterium


ABSTRACT: Avian bacterial pathogen M. gallisepticum is a good model for transcriptional regulation studies due to its small genome and relative simplicity. Here we used RNA-Seq combined with MS-spec proteomics to accurately map coding sequences (CDSs), transcription start sites (TSSs) and transcription terminators (TTs) and decipher their role in stress-induced transcriptional response.

The avian bacterial pathogen Mycoplasma gallisepticum is a good model for systems studies due to small genome and simplicity of regulatory pathways. In this study, we used RNA-Seq and MS-based proteomics to accurately map coding sequences, transcription start sites (TSSs) and transcript 3'-ends (T3Es). We used obtained data to investigate roles of TSSs and T3Es in stress-induced transcriptional responses. We identified 1061 TSSs at a false discovery rate of 10% and showed that almost all transcr  ...[more]
