Figure 1.

Schematic representation of deletion constructs of the Arabidopsis AK/HSD promoter. DNA fragment sizes of the different promoter fragments (A–D) are shown on the right. The − and + positions of the truncation sites relative to the putative transcription start site (labeled as 1 on top of the bars) are given to the left and right ends of the construct bars. Different putative regulatory elements are indicated by different patterned boxes and are marked on top of the upper bar. Truncations are aligned and internal deletions are indicated by single lines.
