Figure 6.

The gene expression program change in the light is brought about to a large extent by COP1-dependent photomorphogenesis pathways. A, Expression in leaf primordia of the genes indicated after 7dL + 3dD is shown, plotted on a log₂ scale relative to the levels after 7dL, in the cop1 mutant and its wild type (WT) grown on Suc-containing plates. The inset shows leaf primordia of a 3dD-adapted cop1 seedling. B, Expression of AUX1 after 7dL, + 3dD, and following transfer back to light (times indicated). Error bars indicate se.
