KEGG Enrichment Bubble Chart. A: Positive ion mode (a) D vs Q KEGG enriched bubble chart (b) Z vs D KEGG enriched gas (c) Z vs Q KEGG enriched bubble chart. B: Negative ion mode (a) D vs Q KEGG enriched bubble chart (b) Z vs D KEGG enriched gas (c) Z vs Q KEGG enriched bubble chart. The abscissa in the figure is x/y (the number of differential metabolites in the corresponding metabolic pathway/the total number of metabolites identified in the pathway). The larger the value, the higher the enrichment of differential metabolites in the pathway. The color of the dot represents the p-value of the hypergeometric test. The smaller the value, the greater the reliability of the test and the more statistically significant. The size of the dot represents the number of different metabolites in the corresponding pathway. The larger the dot, the more differential metabolites in the pathway. (If there is no enrichment result, there is no picture). (“D” refer to Artemisia sieversiana. “Q” refer to Artemisia annua. “Z” refer to Artemisia wellbyi)
