Metabolomics profiling in 24 sorghum genotypes across two nitrogen conditions based on 145 confidently annotated metabolites. a Distribution of the 145 confidently annotated metabolites across two treatment conditions. b First two principle component (PC) from PCA. Values in bracket indicate amount of variance explained by each component. c Volcano plot showing the down regulated (yellow), up regulated (green), and unhanded (grey) metabolites under low nitrogen (LN) conditions compare to high nitrogen (HN). d Proportions of the metabolites with know structures more abundant in samples collected from plants grown under HN (green), more abundant in samples collected from plants grown under LN (yellow), and unchanged (gray)
