Differential gene expression in embryo and endosperm responsive to ABA and H₂O₂ treatments during seed germination. a Histogram of differentially expressed genes; b Venn diagram analysis of the differentially expressed genes under the ABA, H2O2 treatment compared to the control group. ABA treated means DEGs in the ABA_embryo and ABA_endosperm; H₂O₂ treated means H₂O₂_embryo and H₂O₂_endosperm. Figure 2B (left) is all the DEGs (upregulated or downregulated) that identified in four groups: ABA_embryo group, ABA_endosperm group, H₂O_{2_}embryo group and H₂O_{2_} endosperm group shared with each other. Figure 2B (right) is 10,185 DEGs in the ABA-treated groups and 3756 in the H₂O₂-treated groups. 3746 DEGs were shared in ABA-treated groups and H₂O₂-treated groups
