Ruckle M, Burgoon L, Lawrence L, Sinkler C, Larkin R. Plastids are major regulators of light signaling in Arabidopsis. Plant Physiol. 2012;159:366-90 pubmed publisher
..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...
Ledger S, Strayer C, Ashton F, Kay S, Putterill J. Analysis of the function of two circadian-regulated CONSTANS-LIKE genes. Plant J. 2001;26:15-22 pubmed
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)...

. Identification of LOV KELCH PROTEIN2 (LKP2)-interacting factors that can recruit LKP2 to nuclear bodies. Plant Cell Physiol. 2005;46:1340-9 pubmed
..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. ..
Kim S, Park H, Jang Y, Lee J, Kim J. The sequence variation responsible for the functional difference between the CONSTANS protein, and the CONSTANS-like (COL) 1 and COL2 proteins, resides mostly in the region encoded by their first exons. Plant Sci. 2013;199-200:71-8 pubmed publisher
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...
Zhang B, Wang L, Zeng L, Zhang C, Ma H. Arabidopsis TOE proteins convey a photoperiodic signal to antagonize CONSTANS and regulate flowering time. Genes Dev. 2015;29:975-87 pubmed publisher
..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. ..
