  1. log2 Cy5/Cy3 ratio = base 2 logarithm ratio of cyanine 5 to cyanine 3. *Results of a search of the promoter regions (500 bp upstream of putative translational start codon) of displayed genes for A. niger XlnR-binding sites containing either 5'-TTAGCC-3' or 5'-GGCTAG-3'. Location relative to start codon. **log2 Cy5/Cy3 ratio observed in microarray hybridizations.
