Figure 5.
GFP-fused PCS1 is localized to the endoplasmic reticulum. Fluorescence signal in leaf epidermal cells (A) and root cells (C) of seedlings expressing 35S:PCS1–GFP. PCS1–GFP is associated with network-like structures of the ER. (B) and (D) show fluorescence signal in leaf epidermal cells (B) and root cells (D) of seedlings expressing free GFP under the 35S control.
