RpoH(II) Activates Oxidative-Stress Defense Systems and Is Controlled by RpoE in the Singlet Oxygen-Dependent Response in Rhodobacter sphaeroides

Photosynthetic organisms need defense systems against photooxidative stress caused by the generation of highly reactive singlet oxygen ((1)O(2)). Here we show that the alternative sigma factor RpoH(II) is required for the expression of important defense factors and that deletion of rpoH(II) leads to...
