The Streptococcus agalactiae transcriptional landscape
Ontology highlight
ABSTRACT: Streptococcus agalactiae, also known as Group B streptococcus, emerged in the 1960s as a leading cause of septicemia and meningitis in neonates. It is also an increasing cause of infections in adults with underlying diseases. To characterize regulatory elements in this species we performed a genome-wide transcription start site (TSS) profiling and whole-transcript sequencing. TSS were identified by using a differential RNA-seq strategy, based on selective Tobacco Acid Pyrophosphatase (TAP) treatment and adapter ligation, which differentiates primary transcripts and processed RNAs. The accuracy and sensitivity of TSS identification were increased by combining differential RNA-seq analyses under eight conditions corresponding to variations in growth conditions and genetic backgrounds. Whole-transcript sequencing used a two-step adaptor ligation-based directional RNA-seq protocol and was performed under two experimental conditions with triplicate experiments to assess variations in gene expression in response to an acid stress
