Fig. 1.

Greening of dark-grown amiR-MGD1 seedlings after illumination. Plants were grown for 4 d in the dark and then illuminated for indicated hours in the absence (−) or presence (+) of DEX. (A) Phenotype and (B) fresh weight of amiR-MGD1 seedlings. Bars in (A) = 5.0 mm. Data in (B) are means � SE from three (0 h) or four (6, 12, 24, 72 h) independent experiments. (C) MGD1 mRNA levels presented as fold difference from the −DEX control at 0 h of illumination after normalization to the control gene ACTIN8. Data are means � SE from 13 (0 ) or three (1, 3, 6, 12, 24 h) independent experiments. Asterisks indicate significant difference from the −DEX control (P < 0.05, Student’s t-test).
