Mutation of RAPTOR1B promotes the greening of etiolated seedlings. A, Representative images of 6-d-old etiolated seedlings after exposure to light for 2 d. Bar = 5 mm. B, Greening rates of etiolated seedlings grown in darkness for the indicated number of days before exposure to light for 2 d. Data are means ± se (n = 3, more than 80 seedlings for each biological replicate). C, Chlorophyll content (μg g⁻¹ fresh weight [FW]) of seedlings grown in darkness for 5 d and exposure to light for 2 d. Data are means ± se (n = 3). Asterisks represent values from rb plants that are significantly different from those from wild-type plants (**, P < 0.01 by Student’s t test).
