Fig. 3. Identification and rank of candidate PAL-1 target genes. (A) A log-scale histogram of the number of genes versus cumulative scores (1-7) from three distinct tests designed to capture a large fraction of candidate PAL-1 target genes (see text, and Materials and methods for details). (B) Hierarchical clustergram for 308 candidate genes; yellow indicates high and blue low relative expression. The three time courses were concatenated end to end for hierarchical clustering but are separated here for clarity.
