Figure 1

The gene constellations found in the Drosophila genome. (A) Solitary genes were defined as genes without adjoining or overlapping genes on either strand within 20 kb (Group SG). (B) Overlapping genes were defined as genes whose 5-prime region is in full or partial overlap with the 5-prime region of another gene (group 5PP), or genes whose coding regions (exons) fully or partially overlap with the coding region (exons) of another gene (group EE), or genes whose coding region (exons) fully overlaps with the introns of another gene (Group 5PI-EI). (C) Chromatin co-clustering genes were defined as genes that co-locate within 20 kb of one another on opposite strands (Group COS), or as genes that co-locate within 20 kb of one another on the same strand (Group CSS). This group was considered because it has been shown that co-clustering within such distances results in non-independent expression [11, 13].
