Genomic map of 'hybrid' clusters of genes deregulated by TRX in D. melanogaster. Computational identification of clusters was performed on a set of up- and down-regulated genes in the microrray. The new hybrid clusters of genes are indicated with a blue triangle. The clusters detected before - using one of both sets - are indicated with a red triangle (up-regulated genes) or a green triangle (down-regulated genes). Some of them have been enriched using genes expressed in the opposite sense (displayed in light red or light green).
