ELF3 protein levels integrate photoperiod information. A Overlap between PHYC and ELF3 bound genes. B PHYC dark reversion has a half-life of about 8 h. Line A, y =  − 0.094x + 6.476 (linear regression function), BdPHYC in Arabidopsis phyAB double mutant background; Line B, y =  − 0.12x + 6.515 (linear regression function), BdPHYC in B. distachyon WT background. C–D Night length but not day length is the key determinant of when plants will flower. Numbers represent day length (hour): night length (hour). E The YHC mutation restores flowering under short day conditions. p-value was calculated by chi-squared test; the experiment was terminated after 100 days.
