The REVEILLE Clock Genes Inhibit Growth of Juvenile and Adult Plants by Control of Cell Size.

The circadian clock is a complex regulatory network that enhances plant growth and fitness in a constantly changing environment. In Arabidopsis (), the clock is composed of numerous regulatory feedback loops in which () and its homologs and act in a partially redundant manner to promote clock pace. Here, we report that the remaining members of the clade, and , play only minor roles in the regulation of clock function.
