| Outline of Final Research Achievements |
Circadian rhythms is an endogenous oscillation with a period about 24 hr. In order to understand molecular mechanism underlying circadian clock in plants, we performed functional genomic approaches. This project found that Arabidopsis CCA1, a morning-expressed clock-associated transcriptional factor, directly regulates a set of clock-associated genes expressed in the evening. Furthermore, CCA1 directly regulates key genes involved in environmental stress responses. These genes are expressed in the evening. This study illustrates that direct binding by CCA1 in the morning defines strong repression in a genomic scale.
