Genetic analysis of the early flowering 3 (elf3) mutant of Arabidopsis thaliana indicates that ELF3 plays key roles in the regulation of plant morphology, flowering time and stress response, all of which are controlled by circadian clock. Although ELF3 appears to have multiple functions and has been shown to interact physically with the photoreceptor phyB, its ability to regulate several distinct signalling pathways has not been elucidated. This lack of information is attributable in part to the uniqueness of the ELF3 gene, which encodes a novel nuclear protein with no significant sequence similarity to any characterized protein in the existing public databases. Further, little is known about direct protein-protein interactions of ELF3, or about mutations that suppress elf3, phenotypes. Therefore, it is difficult to hypothesize about potential factors downstream of ELF3. In this chapter, we summarize recent progress on the characterization of ELF3 and discuss potential roles of ELF3 in plants. Several reports have demonstrated that a circadian clock affects stress responses in Arabidopsis and that DREB1A/CBF3 mediates between the clock and cold-inducible gene expression. Therefore, possible roles of clock genes such as ELF3, PRRs, LHY and CCA1 in the environmental stress responses of Arabidopsis are also discussed.
