The largest principal component, pathway enrichment, heat map analysis of HDS and HDK based on untargeted metabolomics. (A) The largest principal component plot of HDS (in green) and HDK (in red). (B) Pathway enrichment bubble plot related to HDS. The bubbles’ size and darkness pf the color represented the count and level of the enrichment for terpenoids. The mutation types (HDK) and wild types (HDS) at the mature stage.
