Fig. 3. A gene expression profile during the dauer exit and L1 starvation timecourses. A self-organizing map was used to cluster the 1984 dauer-specific genes with common normalized expression patterns into 45 nodes using 1.5x10⁷ iterations. Each row represents the average expression pattern of the genes in the node (14-100 genes, average of 45). The columns represent different times during the timecourse except for the first column (D/L1) which is the ratio of dauer to L1 at 0 hours. The nodes have also been aggregated into five groups (vertical axis) based on the dauer exit timecourse expression patterns as labeled. These groups are partitioned into many nodes because the expression patterns in the L1 starvation timecourse and relative dauer-enrichment are different. Because normalized data are shown, there are no units on the scale bar. D, Dauer; L1, L1 larvae.
