Scheme of gene regulatory pathways revealing the top five master regulators (pink filled boxes) for eggshell strength at Time Point 2 (ESS2) following the “upstream analysis” [42]. The master regulators written in dark blue and surrounded by dark blue boxes (Prox1, St8sia2 and Tead2) were identified specifically for ESS2 while master regulators written in dark red and surrounded by dark red boxes (Slc22a1 and Sox11) were identified at both time points (corresponding networks for eggshell strength at Time Point 1 (ESS1) in Figure 5).
