Fig. 2.

Dynamics of phyB under persistent shade. Shown are cell and nuclear fluorescence driven by the p35S:PHYB-GFP transgene in mesophyll cells of the cotyledons, the epidermal and subepidermal cells of the hypocotyl (epidermis +), and the vascular tissues of the hypocotyl as affected by CS and PS. (A) Means ± SE (whenever larger than the symbols) of at least 24 seedlings. **P < 0.01. (B) Representative confocal images of the epidermal and subepidermal cells of the hypocotyl. (Scale bar = 25 µm.)
