Digging deeper into the PpsR regulon of Rhodobacter sphaeroides

ABSTRACT: The expression of genes involved in photosystem development in Rhodobacter sphaeroides is dependent upon three major regulatory networks: FnrL, the PrrBA two-component system and the AppA-PpsR pathway. A PrrA- mutant strain of R. sphaeroides is unable to develop under photosynthetic conditions, but when combined with a ppsR mutation, is able to resume growth. In an effort to better characterize the ppsR regulon and to unravel the relationship between the PrrBA and the AppA-PpsR networks, we compared transcriptome profiles from the wild type, PrrA- and PrrA-PpsR- strains under a permissive, common, growth condition: anaerobic-dark-DMSO. Here is stored the microarray data for the PrrA-PpsR- double mutant strain grown under this condition. Keywords: transcriptome profile Rhodobacter sphaeroid
