Figure 3.
The expression levels of anthraquinone related genes in the hairy roots of R. yunnanensis. The pathways were re-drawn refering to the literatures [16,17,18,19,38]. Subfigures: the hairy roots were treated by MeJA. 0, 1, 6, 12, and 24 h and each x-axis represents the time points (hours) of each sample; gene expression levels in y-axis were quantified using RT-qPCR; heatmaps were plotted in Heatmapper (http://www.heatmapper.ca/expression/, accessed on 25 May 2021).
