Global Expression Analysis of Quorum Sensing-Controlled Genes by RNAseq

: RNA sequencing (RNAseq) enables transcriptional profiling of many organisms. This chapter describes the use of RNAseq in prokaryotes to identify quorum sensing (QS)-controlled transcripts by comparing samples from QS-induced and -uninduced conditions. Briefly, each RNA sample is converted to ds-cDNA in a method that limits amplification of ribosomal RNA species. The ds-cDNA contains adapters that enable sequencing and quantification by next-generation sequencing (NGS).
