A novel repressor for expression of a type 6 protein secretion system links nitrogen signaling with beneficial plant-microbe interactions

To investigate the regulon of the novel transcriptional regulator TssR discovered in our study We then performed gene expression profiling analysis using data obtained from RNA-seq of wild type Azoarcus olearius sp. BH72 and tssR deleted mutant cultured under microaerobic conditions with additional ammonium Overall design: Comparative gene expression profiling analysis of RNA-seq data for WT and BH?tssR cultured under non-nitrogen-fixing conditions
