Gene expression in the wild type + relA+ and wild type + relAE335Q strains of Synechococcus elongatus PCC7942 after induction of expression of RelA+ or RelAE335Q with theophylline at subjective dusk - RNA sequencing during constant light conditions. Synechococcus elongatus PCC 7942 = FACHB-805

We investigated the role of ppGpp in Synechococcus elongatus PCC7942 in constant light. We performed RNA-seq experiments using wild type + relA+ and wild type + relAE335Q strains after induction with theophylline starting at subjective dusk. We show that ppGpp induction inhibits global transcription in light. Overall design: Enriched mRNA was prepared from synchronized S. elongatus cells at indicated time points using the Illumina TruSeq Stranded mRNA Sample Prep Kit and Illumina HiSeq technology.
