Total and Polyadenylated RNA profiles of the Maternal Transcriptome. (a) Barplots to show gene specific distribution of log2 RPKM ratios during early development. (b) Heatmap to show stage specific comparison between PolyA+ and RZ data. The barplots to the right of the figure represent average PolyA+ and RZ ratios per stage for the same cluster numbered to the left of the heatmap. Gene names are representative examples from the corresponding cluster. (c) Heatmap to show abundance of polyadenylated maternal genes from six developmental time points. Gene names are representative examples from the corresponding cluster. The heatmaps (b and c) show scaled expression values (the sum of expression per gene across all stages is set to one). PolyA+(RNA harvested with double PolyA+ selection), RZ (ribosomal rRNA depleted-total RNA).
