DREB2A function in repression of PhyB-mediated light signaling and has an opposite effect on flowering time compared to Med25. (A) Hypocotyl-length in dark (gray), red light (white), and the hypocothyl length inhibition (black) of 6-d-old seedlings of the indicated genotypes grown for 5 d under 10 μmol m-2 s-1 of red light or in dark. The experiment was performed using five plates of at least 20 seedlings for each treatment and genotype. (B) Flowering time of the different genotypes grown under LD conditions (16 h light/8h dark; 22 °C/16 °C). The data in A and B represent mean ± standard deviation of at least three individual experiments. (C) A representative picture of the different indicated phenotypes cultivated in LD conditions for 4 wk. (D) A model for how the DREB2A-Mediator interactions regulate flowering time in response to light quality. The DBD, RD, Med25 interaction domain (ID), and AD of DREB2A are indicated. MedX and MedY represent two as-yet unidentified Mediator subunits.
