Figure 7
Expression clustering of known and novel miRNAs; the latter class is labeled in red. Expression levels were normalized per gene (retaining the relative shape but not the absolute magnitude of the temporal expression profiles), and the genes and time-points were clustered with complete linkage using the centered correlation coefficient. Five high-level clusters emerged and are shown here (The base of the tree, showing the relationships between these clusters, is not particularly informative and is not shown.). Emb, embryo; L, larval stage; yAd, young adult.
