Fig. 2. Expression analysis of ATML1 promoter regions. Deletions of promoter regions A, B, C and D are illustrated to the left; corresponding GFP expression patterns at the one-cell stage (early embryo) and heart stage (epidermis) are shown to the right. Presence or absence of GFP expression (green or yellow) are indicated by + or -, respectively. ^*1, one of nine lines showed expression at the one-cell stage; ^*2, no GFP expression in the apical half of the embryo proper; ^*3, GFP expression only in the central region of the embryo. In the schematic, the arrow (top diagram) indicates the transcription start site (+1); 35Smini, minimal promoter derived from the cauliflower mosaic virus 35S promoter. Scale bars: 10 µm.
