Clusters are enriched in genes expressed in particular tissues. (a) From left to right: tissue distribution of genes expressed 18 h before larval to pupal metamorphosis according to Li et al. ; expression pattern of genes included in our trx microarray; genes deregulated by TRX; and genes in clusters deregulated by TRX. (b) Tissue distribution of clustered genes (at least one gene must be expressed in that tissue). Clusters that contain genes annotated as structural proteins in GO are displayed for comparison.
