Regulon controlled by the sRNA PsrR1. Based on the functional enrichment analysis of its computationally predicted targets, PsrR1 is predicted to control genes (orange squares) that encode proteins involved in photosynthesis and tetrapyrrole metabolism (Georg et al.2014). Those genes that were verified experimentally in a heterologous reporter assay as PsrR1 targets are labeled by a black square, and targets suggested by microarray analysis (Georg et al.2014) by a blue square. The computational predictions were done using CopraRNA (Wright et al.2013, 2014). All top 15 CopraRNA target predictions are shown plus selected genes from the top 85 predicted candidates that were functionally enriched.
