Transcriptional landscape of early Platynereis embryogenesis. 13,160 expressed genes (FPKM > 1 in at least one stage) were clustered into 15 groups according to the time series patterns. The developmental expression profile for each individual cluster is shown on the right and includes the number of genes within this cluster. The heatmap on the left is divided horizontally with white lines into the 15 clusters, denoted by C1-C15. Clusters 1–4 correspond to genes with high maternal contribution and Clusters 10–15 are those with later zygotic expression. Clusters 6–8 represent early peaks of zygotic transcription and Clusters 5 and 9 have more stable expression throughout all stages. All individual genes, including expression profiles and annotations for each of the 15 clusters, are listed in Additional file 12: Table S8
