Plants were grown under 12 h light/12 h dark, ∼200 μE light intensity. Data for >T3 plants are means ± SE from three replicate plants with three independent analyses for each plant. Data for F2 progeny represent triplicate analyses of five plants (see supporting information).
UV absorbance at 510 nm.
