Genes identified in the gene regulatory network in Ciona central nervous system formation (‘CNS genes’) according to Imai et al. [30]. a Distribution of CNS genes in the 24 coexpression modules identified within the embryonic transcriptome. Note that CNS genes are present in 20 out of 24 modules but are well represented in the buffering module (Module 23), shown in blue; Module 1 is shown in green. b Correlation coefficients of all the CNS genes to each individual MDBG (white box-plots). Blue box-plots show correlation coefficients of each MDBG with the other MDBGs. All the values are shown in Additional file 8: Table S10 and Additional file 7: Table S9. c Correlation coefficient values of individual CNS genes to all the MDBGs (individual CNS-genes arrayed on x-axis). The CNS genes on the x-axis are in the same order shown in Additional file 7: Table S9; the CNS genes in the buffering module (Module 23) are indicated by the red box. Red line shows 0.9 in correlation coefficients. Red line shows 0.9 in correlation coefficients
