Localization of fluorescent DAYSLEEPER fusions in Arabidopsis root cells. A. An overview of the apical part of a seedling root, showing the predominant nuclear localization of GFP:DAYSLEEPER:HA. The white “B” and “C” indicate at which position of the root the pictures in panel B and C were taken (B and C are derived from different roots). B. depicts root epidermis and cortex cells and C. root cap cells, showing vesicles and membranes (FM4-64) or GFP fluorescence (DAYSLEEPER), or both (merge). Vesicular colocalizations are marked with arrows. The scale bar in A represents 50 μm. The scale bars in B and C represent 10 μm.
