Fig. 4. Effects of small deletions within region D on ATML1 promoter activity. To the right of each deletion construct, presence or absence of promoter activity at the one-cell stage (early embryo) and heart stage (epidermis) are indicated by + or -, respectively. 35Smini, 35S minimal promoter; n.d., not done; ^*1, only six of 20 transformants showed expression; ^*2, only four of 22 transformants showed expression. Scale bars: 10 µm.
