Each square in the heatmap located beside the gene names corresponds to the average FPKM value of the gene in each sample as illustrated in the legend. Genes with significant expression changes compared with the control group (fold change ≥2 and divergence probability ≥0.8) in each development stage are indicated by asterisks (*) in the squares
