Redox rhythm reinforces the circadian clock to gate immune response

摘要

Recent studies have shown that in addition to the transcriptional circadian clock, many organisms, including Arabidopsis, have a circadian redox rhythm driven by the organism's metabolic activities(1-3). It has been hypothesized that the redox rhythm is linked to the circadian clock, but the mechanism and the biological significance of this link have only begun to be investigated(4-7). Here we report that the master immune regulator NPR1 (non-expressor of pathogenesis-related gene 1) of Arabidop
