When an Arabidopsis leaf is exposed to bacteria on the leaf surface, or to the MAMP flg22, the stomatal apertures closed by LRR receptor-like kinase FLS2, as well as a heterotrimeric G protein.

Orc2-5 binds strongly; Orc6 binds weakly to ARS and has a nuclear localization signal that must be activated by the cyclin/ CDK kinase during the G1 to S transition.

trp operon can run even in the presence of repressor. The attenuation system permits another 10-fold control over the operon’s activity. 

Thus, the combination of repression and attenuation controls the operon over a 700-fold range, from fully inactive to fully active: (70-fold [repression] X 10-fold [attenuation] = 700-fold).
