FIG 1.

Global control of flagella. This figure has been modified from a previous review article (142). Positive effects on transcription are indicated by black solid lines and arrowheads; negative effects on transcription are indicated by black dashed lines with blunt ends. The green arrow indicates positive posttranscriptional regulation, and the red dashed lines with blunt ends indicate negative nontranscriptional regulation. Regulators that exert a direct effect on their targets are shown in boxes. The control of flagellar rotation by the CheA/CheY system is included in the figure. The flagellar motor complex is reprinted from reference 143 (CW, counterclockwise). All global regulators, as well as response regulators of 2CSTSs, are boxed. Sensor kinases are not boxed.
