Overview of the Embryonic Transcriptome. (a) Density plot to show distribution of Maternal-Embryonic (grey) and Embryonic (red) ratios of polyA+ vs. RZ expression (RPKM) at Stage 9. (b) Heatmap to show dynamic expression of 2,481 polyadenylated embryonic genes. Scale represents the log2 transformed RPKM values. Gene names are representative examples from the corresponding cluster. (c) A pie-chart to show percentage of genes whose expression is increased four folds or more relative to Oocyte. (d) A heatmap to show scaled expression (the sum of expression per gene across all stages is set to one) of 2,481 polyadenylated embryonic genes. Gene names are representative examples from the corresponding cluster. (e) A pie-chart to show percentage of embryonic genes peaking in expression per stage.
