From: Transcription-associated metabolomic profiling reveals the critical role of frost tolerance in wheat
Differentially accumulated metabolites of wheat in response to cold stress. A PCA plot of metabolomic results. B Numbers of differentially accumulated metabolites under different treatments. C Venn diagram of differentially accumulated metabolites (FDR < 0.05 and FC ≥ 2). D, K-means clustering analysis of the differentially accumulated metabolites into nine clusters according to their expression profile. The cluster names and the number of metabolites for each cluster are indicated. CK1, before treatment Jimai 325; CK2, cold treatment Jimai 325; MU1, before treatment MU-134; MU2, cold treatment MU-134
