udu genetically interacts with nkx2.5 to maintain ventricular identity. Confocal immunofluorescence images of ventral views of WT (A), udu−/− (B), nkx2.5−/− (C), and udu−/−; nkx2.5−/−(D) zebrafish hearts at 48 hpf with showing the myocardium (MF20, blue) and atrium, (S46, green), and nuclei of cardiomyocytes (Mef2, red). Proportion of total cardiomyocytes with ventricular identity at 48 hpf in WT (grey), udu−/−;nkx2.5+/+ (blue) udu+/+;nkx2.5−/− (red) and udu−/−;nkx2.5−/− (purple) embryos (E). ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001, ∗∗∗∗p < 0.0001, error bars = SEM. Scale bars represent 50 μm.
