Dissecting M and G1 phase subnetworks. A) A network of M and G1 phase gene modules are shown, sorted by mean phase. If a TF is found to be a regulator for a module then it is depicted with a purple square. Potential regulation of M phase modules by SPBC19G7.04 is pointed out with an arrow. B) Early M phase gene regulatory network in which TFs are shown in ellipses, and the rest of the genes in boxes. The colors of the nodes are according to their peak phase, where more reddish colors represent phases that are later in M and thereafter, while more orange and yellow hues depict earlier (late G2 and G2/M) phases. The regulatory hub for the early M phase TF SPBC19G7.04 is marked with an arrow.
