A. Arabidopsis seedlings grown in light (deetiolated) or dark (etiolated). B. Different aspects of light detection are experienced by seedlings in their initial phase of growth.
Figure 2.
Figure 2.
A simplified model of cross-talk during seedling photomorphogenesis. Factors mentioned in the text and known to connect at least two response pathways are shown. Large ovals represent major input pathways. Associated factors are shown as smaller ovals attached to these pathways. Cross-talk between pathways is represented by lines connecting pathways or connecting individual proteins where these have been identified. Dashed lines represent relationships that are not well-characterized in the literature to date.
