Abstract

RNA-sequencing has revolutionized the quantitative and qualitative analysis of transcriptomes in both prokaryotes and eukaryotes. It provides a generic approach for gene expression profiling, annotation of transcript boundaries and operons, as well as identifying novel transcripts including small noncoding RNA molecules and antisense RNAs. We recently developed a differential RNA-seq (dRNA-seq) method which in addition to the above, yields information as to whether a given RNA is a primary or processed transcript. Originally applied to describe the primary transcriptome of the gastric pathogen Helicobacter pylori, dRNA-seq has since provided global maps of transcriptional start sites in diverse species, informed new biology in the CRISPR-Cas9 system, advanced to a tool for comparative transcriptomics, and inspired simultaneous RNA-seq of pathogen and host.
