    ..We conclude that the integration of light and plastid signaling regulates a number of END genes that help optimize chloroplast function and that at least some END genes affect photosynthesis-related gene expression...

    The Arabidopsis genes CONSTANS-LIKE 1 (COL1) and CONSTANS-LIKE 2 (COL2) are predicted to encode zinc finger proteins with approximately 67% amino acid identity to the protein encoded by the flowering-time gene CONSTANS (CO)...

    ..Furthermore, the CFP-LKP2 and YFP-CO signals co-localized with signals for pU2B''-mRFP, which is a marker for Cajal bodies. These results suggest the possibility that LKP2 functions with CO/COL family proteins in the nuclear bodies. ..

    Although the protein CONSTANS (CO) and its close relatives CONSTANS-like (COL) 1 and COL2 exhibit high amino acid sequence similarities, only the CO protein regulates floral induction in Arabidopsis...

    ..In addition, TOE1 interacts with the LOV domain of FKF1 and likely interferes with the FKF1-CO interaction, resulting in partial degradation of the CO protein in the afternoon to prevent premature flowering. ..
