Transcripts of the six genes/gene families in bold type were detected in the notochord when Ci-MRF was expressed in that lineage; transcripts of the four genes/gene families in regular type were not detected in the notochord under those conditions. CHIP assay data are from Kubo et al., 2010; “+” signifies an association of CiMRF with chromatin of the indicated gene and “−” signifies no association of CiMRF with chromatin of the indicated gene. E-box data are from Brown et al., 2007; “+” signifies the presence of at least one E-box that is important for expression, “−” signifies that no E-box important for expression was found and “X” signifies that no member of in the indicated gene/gene family was examined.
