Heatmap of DEGs involved in cell growth and cell wall modification. The expression levels of DEGs in TPM were compiled with Excel 2007, normalized using a log2 base method, and exported to the HemI toolkit124. The Heatmap was generated using the default parameters. The expression levels are presented as different colors, and the values are defined in the scale bar. PL, the primary laticifers; SL, the secondary laticifers.
