Lack of RsmA-Mediated Control Results in Constant Hypervirulence, Cell Elongation, and Hyperflagellation in Pectobacterium wasabiae
Figure 2
In Pectobacteria rsmA expression level affects transcriptome.
A global mRNA profile of the rsmA− of Pw was compared with its parental strain. The results were compared with a previous study of the expI− strain of Pa [3]. In the expI− strain the RsmA level is increased [7]. The genes included in the figure are those which passed two criteria: firstly, the expression level changes were in the opposite direction in response to rsmA inactivation as compared to rsmA up-regulation (expI− strain); secondly, the genes have been associated with virulence. The scale bar(top of figure) represents the fold change in mRNA levels between the wild-type and the rsmA− Pw strain, with positive values representing up-regulation and negative values representing down-regulation in the rsmA− strain.
