Figure 5.

Upstream sequence of the LeExt1 gene. Bold letters underlined with dashed arrows indicate putative binding sites of transcription factors P, MYB.Ph3, SBF-1, and Athb-1 as determined using TFSEARCH. Bold arrows on top of a base indicate the start of the different promoter fragments as indicated to the right. The TATA box is underlined and indicated in bold. An asterisk indicates a stop codon upstream of the open reading frame (ORF) in the genomic sequence. Amino acids encoded by the ORF are given in the one letter code. Bold letters designate the N terminus of the LeExt1 protein.
