Clustering of differentially expressed transcripts identified in the pairwise comparisons between embryo developmental stages. The analysis included DETs with a FC > 2 and RPKM > 10. For each transcript, RPKM values were normalized to its maximum RPKM value during embryo development. Normalized values were subjected to k-means clustering method and classified into 12 different clusters, based on their expression level across the four developmental stages. The Y-and X-axis represent relative expression (from 0 to 1) and different embryo developmental stages, respectively. Enriched processes and functions and their enrichment level (FDR) are presented for each cluster. The level of enrichment is proportional to colour intensity
