Fig. 4. Hierarchical cluster analysis of lin-35-, efl-1- and
dpl-1-regulated genes. The 272 genes are displayed in rows;
columns represent the average of repeats for each mutant (D, dpl-1;
E, efl-1; L, lin-35). Red, lower expression in mutant
samples relative to controls; black, equivalent expression in mutant relative
to control; green, higher expression in mutant relative to control
samples.
