FIGURE 5.

Motif occurrences in the P. patens lhcsr1 promoter. The promoter sequence was screened against the plant cis-acting regulatory DNA elements database PLACE (A) and the plant cis-acting regulatory element database PlantCARE (B). The 1,956 bp upstream region of the lhcsr1 gene was split into four regions based restriction enzyme sites (cf. Figure 4). The four regions are marked by dashed lines. Colored lines mark occurrence of light responsive elements (green), TATA box motifs (blue), and enhancer element motifs (yellow). Motifs situated on the plus and minus strand are shown. Position of the 5′ untranslated region (5′-UTR) and the start codon of the lhcsr1 gene (ATG) are shown. PlantCARE database only used the first 1.5 kbp of the promoter sequence. Regions I and II need to be present to achieve full promoter activity.
