The competition between interaction and temperature shows that with the increase of the anisotropic parameter, the critical on-site repulsive interaction for the metal-insulator transition increases for fixed temperature. The interaction-anisotropic parameter phase diagram reveals that with the decrease of temperature, the critical anisotropic parameter for the Mott transition will increase for fixed interaction cases.展开更多

In Arabidopsis, most circadian-clock components act in the nucleus as transcriptional regulators and generate rhythmic oscillations of transcript accumulation. In this review, we focus on post-transcriptional events that modulate the activity of circadian-clock components, such as phosphorylation, ubiquitination and proteasome-mediated degradation, changes in cellular localization, and protein-protein interactions. These processes have been found to be essential for circadian function, not only in plants, but also in other circadian systems. Moreover, light and clock signaling networks are highly interconnected. In the nucleus, light and clock compo- nents work together to generate transcriptional rhythms, leading to a general control of the timing of plant physiological processes.展开更多
