The Gene expression: This figure represents the normalized transcript level (read number per coding length per million reads) for each gene across the developmental stages including 18 embryo stages, four larval stages (L1-L4), and young adult. To facilitate comparison, we subtract each gene expression values in different periods from the average value of the gene expression in different periods. The heatmap represents normalized transcript level from high (pink) to low (skyblue). Eight distinct modules that are based on their expression pattern are shown by colored modules. Yellow, Turquoise, Red, Purple, Blue, and Black: early-embryonic; Magenta: early- and mid-embryonic; Tan and Brown,: mid-embryonic; Green: late-embryonic; Greenyellow: early-, mid- and late-embryonic; Pink: larval
