FIG 6.
Portion of the P. syringae AlgU regulatory network controlling flagellar motility and alginate production. AlgU coordinates alginate production and suppression of motility by controlling the expression of genes necessary for these functions. AlgU also controls the expression of additional regulators, like AmrZ, which promotes alginate production and motility (67). FleQ is the master regulator of flagellar gene expression, and fleQas promotes motility when AlgU is expressed. The arrows and T-shaped bars indicate positive and negative effects on expression or function, respectively.
