Rhythmic and selected CAM photosynthesis-related metabolites in C. mannii.

(A) Hierarchical clustering metabolic abundance profiles throughout the diel cycle. The abundance values (log2) were averaged from six replicates, and the Z score was transformed. The metabolite annotation is summarized in Supplemental Table 10.

(B) Rhythmic metabolites and their functional categories.

(C) Peak times of rhythmic metabolites across the 24-h diel cycle.

(D) Distribution of rhythmic metabolites in the seven major categories.

(E) Abundance profiles of selected metabolites from secondary mass spectrometry (malic and fumaric acids) and primary mass spectrometry (potentially fructose, glucose, oxaloacetic acid, and pyruvate). Standard errors of six replicates are indicated by error bars.
