Broad, overlapping patterns of binding of transcription factors to the genome in blastoderm embryos. Data are shown for eight early A-P factors (green), six pair rule A-P factors (yellow), seven D-V factors (blue), and two general transcription factors (red). The 675-bp ChIP/chip window scores are plotted for regions bound above the 1% FDR threshold in a 500-kb portion of the genome. The locations of major RNA transcripts are shown below in grey for both DNA strands. The genome coordinates are given in base-pairs. For those factors for which ChIP/chip data are available for more than one antibody, data are shown for the antibody that gave the most bound regions above the 1% FDR threshold using the symmetric null test.
