| Study Title | Effects of different planting densities on the metabolism of Panax notoginseng |
| Study Type | Planting density experiment |
| Study Summary | At the moderate planting density, the primary metabolism (starch and sucrose metabolism) of the plants were significantly enhanced. However, the strong intraspecific competition at the higher planting densities resulted in stress as well as the accumulation of antioxidants (gentiobiose, oxalic acid, dehydroascorbic acid) and other stress resistance-related metabolites. Interestingly, the planting at low densities with low intraspecific competition disturbed normal carbohydrate metabolism by upregulating galactose metabolism. |

| MS Comments: | Mass spectra were obtained in electron impact (EI) ionization mode at 70 eV by monitoring the full-scan range (m/z 45-600);the raw peak obtained by data baseline filtering and calibration, peak alignment, deconvolution analysis and peak identification using MS-DIAL with the Fiehn library. The peak areas of metabolites in raw MS-Dial output (Supplementary Table S2) were normalization by sum, transformation by log and scaling by Pareto method on Metaboanalyst 4.0 (http://www.metaboanalyst.ca/MetaboAnalyst/) |
| Ion Mode: | UNSPECIFIED |
