Extended Data Fig. 8 — a) WGCNA cluster dendrogram reveals 9 clusters of co-expressed genes, or modules. The four modules with significant correlations to drought or pre-drought (pink, green, magenta, and brown) are indicated. b) Correlations of the pink, green, magenta, and brown module eigengenes with environmental conditions (pre-drought = 0, drought = 1) and efflux of ¹³C-enriched (VOC ¹³C/(¹²C + ¹³C)) acetate and acetone from chambers receiving ¹³C2-pyruvate (acetate-C2 and acetone-C2, respectively) across three time points (0, 6, and 48 h post pyruvate injection; total n = 27 [3 measurements each for each soil collar receiving ¹³C2-pyruvate]). Pearson correlation coefficients are shown with FDR-corrected p-values below in parentheses. White boxes indicate no correlation (P < 0.1). *, P < 0.05; **, P < 0.01; ***, P < 0.001.
