Keywords: Panax notoginseng; genome; triterpenoid saponins; dencichine EN Panax notoginseng genome triterpenoid saponins dencichine 869 871 3 05/20/21 20210501 NES 210501 I Panax notoginseng i (2n = 2x = 24), reputed as a valuable medicinal plant, belongs to the Araliaceae family (Figure 1a). In conclusion, this high-quality genome assembly of I P. notoginseng i provides novel insights into unique saponins distribution pattern and reveals possible dencichine biosynthetic pathway. The chromosome-scale high-quality genome assembly of Panax notoginseng provides insight into dencichine biosynthesis Gene family analysis of I P. notoginseng i and 11 other angiosperms suggest I P. notoginseng i genes were clustered into 17,306 families and I P. notoginseng i had much less multiple-copy orthologs compared with I P. ginseng i (Figure 1f).
