Hierarchical clustering of miRNA expression.

<p>Normalized expression profiles of 215 miRNA/miRNA*s from six different developmental stages were clustered. Stages are in columns and miRNAs in rows. Red indicates that a gene is represented highly at the stage, whereas green indicates the opposite. miRNAs with similar expression patterns cluster together. There are five Clusters (1–5) with variable numbers of sub-clusters. Abbreviations: <b>E</b>, embryos; <b>L</b>, larvae; <b>P</b>, pupae; <b>M</b>, adult males; <b>F</b>, adult females and <b>B</b>, blood-fed adult females.
