FIG 5 .

Summary of significant differences in expression between the WT and the relA mutant, in both planktonic and biofilm growth, as revealed by RNA-seq. The numbers shown are the number of genes in which expression differs at a very stringent cutoff of q < 0.001; arrow direction should be read as “is less than.” Arrow thickness is proportionate to the number of differences. Boxes containing both arrows denote genes with divergent expression, as follows: 35 genes have reduced expression in the relA mutant biofilm that were increased in the WT biofilm, and 25 genes have reduced expression in the relA biofilm that were increased in the relA planktonic culture.
