The paper shows that nuclear basket proteins NUA and NUP136 regulate circadian period in Arabidopsis by facilitating proteasome-mediated degradation of TOC1.

The paper shows TOC1 phosphorylation enhances chromatin binding at rhythmic gene promoters, specifically at CCA1, and is required for optimal repression of CCA1 but not LHY.

This study identifies HOS15 as a regulator of PRR7 protein turnover, linking circadian rhythms to freezing tolerance through CBF1 and COR15A upregulation in Arabidopsis.
