Overview of collected castor bean samples and transcriptome sequencing. A List of the 16 samples used for transcriptome deep sequencing. Samples S1–S5 represent seeds at five developmental stages, as described previously by Zhang et al. [35]. DAP, days after pollination. Inf, inflorescence. En, endosperm. Em, embryo. B Typical profiles of relative expression levels (as Z-score values) of tissue-specific genes across all tissues. The number of genes belonging to each group is shown above the graph. Gseed, germinating seed. C Heatmap representation of transcript levels of seed-specific genes throughout seed development. The numbers (from I to IX) denote the clusters whose genes exhibited similar expression profiles. D Mean expression of genes within each cluster after normalization (see the “Methods” section). E Heatmap representation of transcript levels of seed stage-specific genes encoding transcription factors (TFs) throughout seed development
