The GtaR quorum-sensing protein negatively regulates a capsular polysaccharide gene transfer agent (RcGTA) receptor on Rhodobacter capsulatus cells. Rhodobacter capsulatus

Expression profiles of wild type and gtaI mutant in logarithmic and stationary phase of growth. The objective was to search for differentially regulated genes potentially associated with EPS production in R. capsulatus. Overall design: A single sample of each strain in both growth phases for basic comparison of expression profiles.
