Fig. 2. Expression patterns of genes in mounts 40 and 41. Hierarchical clustering was used to display the ratio of dauer to L1 at 0 hours and the expression ratios of the commonly regulated genes during the dauer exit and L1 starvation timecourses for the (A) eight genes in mount 40 and (B) seven genes in mount 41. The genes in mounts 40 and 41 have homogeneous expression patterns. The feeding response genes that are in common with the genes in mounts 40 and 41 are indicated with pink bars to the right of the clusters. Rows represent different genes and columns represent different times during the timecourse. Green and red arrows are the dauer exit and L1 starvation timecourses, respectively. Scale shows level of expression. D, Dauer; L1, L1 larvae. Full data for this figure are available at http://dev.biologists.org/supplemental/ and at http://cmgm.stanford.edu/~kimlab/dauer/
