Figure 2.
Analysis of predicted promoters of selected genes. The program TFSearch [30] identified monomeric ROR alpha response elements (grey shading) in promoters of the genes indicated to the left. Analysis with the program EvoprinterHD [32] was used to determine the conservation of the NHR-23/ROR alpha sites and flanking regions across five nematode species (see text). Conserved bases in five out of five nematode species, indicated by capital letters, reveal extensive sequence conservation within and around the putative NHR-23/ROR alpha binding sites.
