Figure 8The gain - of - function lines of all members of the core network were crossed either with each other , referred to as double cross , or with the control line ( GFP - GR ) , referred to as single cross . The projected rosette area of the F1 double and single cross and the GFP - GR , germinated and grown on DEX , was measured at 22 DAS . A representative picture of the single and double crosses is depicted . The values represent the relative increase or decrease in rosette size of the double crosses compared to their parental single crosses . The outcome of every double cross is classified into three groups : additive ( green connections ) , negative ( blue connection ) and synergistic ( orange connections ) phenotype . The precise measurements can be found in Fig EV2 .

Figure 6A549 cells expressing control shRNA, p53 shRNA, or p53 shRNA plus Flag-WDR63 were subjected to wound-healing (A) assays. The shown images are representative of three independent experiments. Data shown are mean ± SD (n=3). **, P ˂ 0.01; ***, P ˂ 0.001; One-way ANOVA.
