Fig. 7: The different growth statuses of Angelica plants and phylogenetic tree of TPS genes.

a Plants were sown simultaneously and grown in the same environment. Samples were taken at the same time for observation and analysis. EF early flowering, NG normal growth. We highlight the highly lignified Angelica root of the EF plant and the normally developed storage root of the NG plant on the right side. b Five TPS subfamilies (TPS-a, TPS-b, TPS-c, TPS-e/f, and TPS-g) were clearly identified. The genes from A. sinensis (QH) and A. sinensis (GS) are highlighted by red and green dots, respectively. The heatmap of gene expression is illustrated.
